Installation and Calibration

Smart Water Valve Installation

Installation of the SMART VALVE™ should be performed by a licensed plumber.

Cut Sheets

Threaded bolts are only provided with certain sizes where our flange holes are threaded. Flanges with standard ‘through holes’ use standard bolts which are typically provided by the plumber. The valves sized 3”, 6”, 10” are threaded, the 4”, 8”, 12” are not. The cut sheets specify which in either case. 

The valve is made in flanged and threaded configurations according to your system pipe design. Installation of the SMART VALVE™ should be performed by a licensed plumber. All installations should include gaskets on flanged units. Please note Victaulic gaskets do not mate up to the SMART VALVE™ without an additional full face gasket that the plumber may need.

Installation Instructions

Important: The valve must not lower the pressure of fire safety equipment and should therefore be installed downstream of that equipment or on a split that would not lower the pressure serving the fire safety equipment.

 

The SMART VALVE™ is installed:

  • On the USER side of the water meter

  • For irrigation applications, downstream of irrigation backflow preventers

  • If the the Fire suppression systems are fed by the same meter and line, downstream from any Fire Split. Some buildings have a separate meter for the fire suppression systems - in that case it is not appropriate to install a Smart Valve on that Fire line.

  • Preferably with 10X the diameter of the pipe distance of straight pipe prior to SV installation location, but not required.

  • For applications where one line feeds the potable water tank and the cooling tower, in a location that will affect the water feeding the cooling tower (but would not lower the fire safety equipment pressure)

  • Some buildings have lines that take water up several floors to a pumping room - with splits on the way up feeding the first several floors. In this case the Smart Valve would be installed before the first floor split (but after any fire line split).

  • Upstream of any splits other than a fire split.*

* Installing downstream of a split that is not generally open should not significantly affect the valve's performance on a daily basis. For instance, if there an upstream irrigation split before the meter, the valve's effectiveness would be diminished while the irrigation system is running.

Incremental savings note: If installing the valve downstream from an irrigation split, try to schedule irrigation so that it does not occur during peak building usage (early morning, after lunch, etc.).

Flanged Installation Steps

Bring Full-flanged gaskets in addition to the Victualic gaskets, if needed.

Bring your own bolts if bolts are not provided. Threaded bolts are only provided with certain sizes where our flange holes are threaded. Flanges with standard ‘through holes’ use standard bolts which are typically provided by the plumber. The valves sized 3”, 6”, 10” are threaded, the 4”, 8”, 12” are not. 

1. Identify installation location and prepare pipe for installation on the user side of the water meter. Install location should be before any other fixtures or devices such as a pressure reducer or booster pump. Immediately after the backflow preventer is often a good place.

2. It is recommended wherever possible (but not critical) to have 10 diameters of straight pipe before and after the valve to ensure there are no turbulence issues. I.e.: 2” valve x 10 dia. = 20” before and after. If you must choose, leave more straight pipe before the valve.

3. Prepare pipe flange spacing to allow for length of valve and gaskets to be installing inline. Valve length varies by size, please see Cut Sheets for exact dimensions.

4. Install using flange gaskets (usually 150 pound gasket) at each flange joint. Note: The Victaulic gaskets do not mate up to SV without an additional full face gasket.

Note: You must bring your own bolts for through bolt fittings

5. Make sure the closed orifice end faces upstream and the open orifice end faces downstream. See flow direction arrow on the valve.

6. Slowly turn water supply back on. Vent trapped air from the water line where possible. Flow may be turbulent until excess air is out of the system.

Threaded Installation Steps - Do not Over Tighten

1. Identify installation location and prepare pipe for installation on the user side of the water meter. Install location should be before any other fixtures or devices such as a pressure reducer or booster pump. Immediately after the backflow preventer is often a good place.

2. It is recommended wherever possible (but not critical) to have 10 diameters of straight pipe before and after the valve to ensure there are no turbulence issues. I.e.: 2” valve x 10 dia. = 20” before and after. If you must choose, leave more straight pipe before the valve.

3. The Smart Valve may be female, male, or male/female threaded. Prepare pipe threading with pipe tape and pipe dope.

4. Make sure the closed orifice end faces upstream and the open orifice end faces downstream. See flow direction arrow on the valve.

5. Tighten ends of pipe onto pipe threading until it is secure with no leaks. Threading is NPT. Do not over-tighten.

6. Slowly turn water supply back on. Vent trapped air from the water line where possible. Flow may be turbulent until excess air is out of the system.

Smart Water Valve Calibration

ADJUSTMENT INSTRUCTIONS

The Smart Valve is an EXTERNALLY ADJUSTABLE device, allowing you to fine tune the spring setting for maximum savings without any negative effects, and to allow you to adjust to any future changes in your water system pressure or flow rate.

Installing a pressure gauge (temporary or permanent) at least a few feet downstream of the Smart Valve will greatly assist in calibrating the valve with your water system, but is not mandatory.

Your goal is to adjust the Smart Valve to the strongest setting tolerable to the system without causing problems or complaints due to too large of a pressure drop. The stronger the setting the more you will save in meter accuracy and water over-consumption.

Once the valve has been properly installed, locate the ‘adjustment windows’ near the center of the valve. Inside are numerous slots designed to fit the adjustment tool. Attach the tool to a 1/2" head ratchet handle. You will insert the adjustment tool pin into one of the slots and rotate the inner collar in either the PLUS (+) or MINUS (-) direction as marked on the valve.

The Smart Valve is delivered to you near the full MINUS setting where there should be little to no effect from the valve. Insert the pin into a slot in the window and rotate the inner collar towards the PLUS side. Each full length of window adjustment is a ‘click’. Each click towards the PLUS side will further increase the backpressure upstream towards the water meter, and should result in a corresponding pressure drop of 1-2 PSI downstream of the valve.

There are approximately 22-23 clicks between full MINUS and full PLUS. If an adjustment needs to be made after the Smart Valve has been in operation for some time, you might experience ‘sticktion’, where it seems the inner collar is ‘stuck’ and the first adjustment will be more difficult. Once you break the ‘sticktion’ with a little extra force the valve will be easier to adjust.

Technical Specs

NSF/ANSI 61 and NSF/ANSI 372

Customized Specifications

Each SMART VALVE™ is built to exacting specifications based on the specific water system parameters. Spring tension is calibrated based on the users’ pressure and flow profile. Connection types are determined by the existing pipe configuration. A completed site survey is required for all orders.

Construction

The SMART VALVE™ is made primarily of Acetron GP, an extremely strong, self-lubricating space-age resin created by Quadrants. Acetron GP is the material of choice when precision parts are required for impact and wear resistance in a wide range of industrial and mechanical applications.  With low, consistent internal stress, this material experiences little dimensional change during use. Acetron GP is also an ideal material for use in wet environments because it resists moisture, will not accumulate particulates, will not corrode and self-seals extremely well eliminating the need for seals and gaskets that would wear out, making Acetron GP the ideal choice for the SMART VALVE. All non- Acetron GP components are manufactured from food-grade stainless steel.

Configurations

The SMART VALVE™ is available in the following standard plumbing sizes: 5/8” 3/4” 1” 1.5” 2” 3” 4” 6” 8” 10” 12” Larger sizes available on a custom order. Sizes 2” and below are female double threaded. Sizes 3” and above are flanged on both ends with a standard bolt pattern. Bolt patterns vary by size. Please see Cut Sheets for your specific size.

Specifications

Valve body, plunger, backplate: Acetron GP Shaft, spring: Food-grade Stainless Steel For dimensions of common sizes please see our Cut Sheets.

The SMART VALVE™ is installed on the USER side of the water meter. The valve is made in flanged and threaded configurations according to your system pipe design. Installation of the SMART VALVE™ should be performed by a licensed plumber and any plumber can easily install the unit. All installations should include gaskets on flanged units or pipe tape on threaded units to prevent water leakage. Please see our detailed Installation Instructions for Flanged or Threaded pipe.
