how it works components Pilot Assembly (Brains) how it works components Diaphragm Chamber diaphragm Diaphragm has a larger surface area than the seat Diaphragm: Larger Surface Area controlled water pressure Controlled water pressure in the diaphragm chamber directly controls the main valve Seat Smaller Surface Area pilot Controls employ special components that utilize upstream pressure and downstream pressure to adjust the water pressure on top of the diaphragm main valve When the pilot opens, the main valve opens When the pilot closes, the main valve closes Main Body Example: Pressure reducing valve plumbed with pilotry set to 70psi resulting in forces the main valve to modulate, maintaining pressure to 70psi

how it works step-by-step 4:34 Video: ACV Animation – How an ACV Works

how it works where is it used Reduces downstream pressure from a high upstream pressure, the same way the pressure reducing valve/regulator on your house works direct acting pressure reducing valves Direct acting PRVs/regulators exhibit fallout. The more flow you put through the device, the lower the downstream pressure automatic control valves Pressure reducing ACVs provide consistent performance regardless of flow rates downstream pressure Used in large applications, it is crucial to maintain downstream pressure and there is a propensity for fluctuations in inlet pressure and flow pressure reducing Over 90% of ACV application are pressure reducing

Pressure Reducing w/ Low Flow Bypass Pressure Reducing with Solenoid Shut-Off Flow rates below the min flow of a standard PRV will cause the valve to chatter and cause noise Ex: During nighttime janitorial service Equipped with a low flow bypass to handle flows from 0-10gpm Bypass valve is set higher than main valve (3-5psi) Used where you not only want to regulate pressure from high to low, but also have the ability to remotely shut off flow through the valve Pressure Reducing with Sustaining Function Pressure Reducing w/ Downstream Surge Protection Regulate pressure from high to low, but also have a critical user, such as a factory or hospital, upstream of the device In the event that demand would normally cause a reduction in upstream pressure, this valve will limit flow, sustaining pressure to that critical user Used where there could be a sudden reduction in downstream flow Creates a pressure surge, similar to water hammer from a fast closing faucet or sprinkler valve Will rapidly close, protecting devices upstream from that surge

ZW209 pressure reducing valve Test Your Knowledge How does a Pressure Reducing ACV function once demand has been induced downstream? Place the following in the correct order: Water begins to flow out of the diaphragm chamber As flow continues the valve modulates to hold a constant outlet pressure The main valve opens allowing water to flow over the seat The pilot senses a drop in downstream pressure and begins to open

features & benefits fire protection control valves 5:13 Video Function of a ZW209FP ZW209FP pressure reducing valve fire protection valves Pressure reducing valve for fire protection applications Only manufacturer UL/c-UL Listed up to 10” FM approved connection types 150# flange 300# threaded 300# flange 300# grooved

features & benefits fire protection control valves Fire systems can be complex, encompassing multiple control valve functions in order to provide adequate building safety pressure reducing valve Pressure reducing ACV rates are approved for use in fire systems Function identical to the standard PRV (reducing downstream pressure) In a fire system, the downstream devices that need consistent pressure to operate are fire sprinklers and hoses fire pump relief valve Relief valve, generally plumbed in a branch from the main fire plumbing line In the event that the upstream pressure exceeds a present limit, valve will open, dumping/relieving pressure from the main pump suction control valve Sensing line plumbed to the inlet of the fire pump Pump begins to overdraw from the supply line (supply network) Valve will begin to close, presenting a risk of damage to the supply network

features & benefits automatic control valves relief / sustaining The majority of application for a relief/sustaining valve are identical to the function in fire protection Plumbed in a branch line and will open to relieve pressure from a pump Could also be plumbed inline (not a branch line) When plumbed inline, a ZW205 will sustain pressure upstream of the valve check valve Generally used after a pump to prevent damage from backflow Fully opens when inlet pressure is greater than outlet pressure Closes drip tight when outlet pressure is greater than inlet pressure

features & benefits automatic control valves excess pressure shut-off Where safety-system redundancy is required with a pressure reducing valve Where there is a failure of the PRV, or if the PRV cannot react quick enough to a spike Shut-off valve will take over shutting down the system until the pressure comes back within an acceptable range Great in high rise buildings float level control valve Maintains fluid level in a tank or reservoir When level lowers, float drops and valve opens When float reaches set-point, valve closes Remote mounted float pilot is standard Valve mounted float option (as shown) ZW204

features & benefits automatic control valves Solenoid control valve Opens or closes based on an electrical signal from a remote location Identical to the sprinkler valve that waters your lawn, only much larger, more robust pilot operated valve Ideal for applications where you need to: Control on/off flow over long/remote distances Hazardous environments Part of an automated system or process equipment Connects to stand alone control systems or master control systems On/Off water control via electrical signals 24, 120, 240, 480 VAC 6, 12, 24, 120, 240 VDC
