PRESSURE REDUCING VALVE (PRV) 

 

Watts Series 115 Pressure Reducing Valves (PRV)

 

   

 

• Limits downstream pressure to pre-set maximum

• Maintains constant maximum outlet pressures
• Typically used in commercial and industrial installations where downstream devices require protection from fluctuating supply pressure
• Automatically reduces higher inlet pressure to a constant outlet pressure
• Unaffected by changing flow rates or inlet pressures
• Precise alignment and stable throttling
• Synthetic rubber/nylon diaphragm creates variable volume chamber
• Drip-tight, dynamic quad seal
• Fused epoxy coated, cast iron construction for maximum service life
• Please specify required kPa setting at time of order

 WATTS AUTOMATIC CONTROL VALVE

 Automatic Control Valves

Performance is standard: The design and innovative features incorporated into every Watts Automatic Control Valve means consistent,dependable, high performance, positive control andlong life.
Efficient design: The main valve, globe or angle pattern, is diaphragm actuated, hydraulically operated. It consists of only fourmajor components. 
Drip tight seal: Watts ACV leads the automatic valve industry by beingthe first to incorporate the dynamic quad seal. The seat,retained on 3 1/2+ sides, provides positive closurewhile eliminating the need to “bite” into the seal, 
Fused epoxy prolongs life: This coating is applied under rigorous preparation andapplication standards. It is non-porous, improving theflow coefficiency of the valve and effectively sealing thecasting from interaction with the controlled liquid. Thecoating also protects the valve from environmentalattack.
Right place, Right time: Watts ACV is committed to providing you with correctfunction and material to meet your applicationrequirements and prides itself with accurate, calculateddelivery schedules.

PRESSURE RELIEF VALVE

WATTS, PRESSURE RELIEF VALVE, M116

 

Description:

The WATTS ACV Pressure Relief, Sustaining or Backpressure Control Valve is designed to permit flow when upstream pressure is above the adjustable setpoint of the control pilot, and throttle toward closed when upstream pressure falls below the adjustable setpoint.

When the valve is installed "off the main line" on the branch of a tee, it serves as a Pressure Relief Control Valve. It is normally closed, and quickly opens when upstream pressure exceeds the pilot setting, relieving excess pressure.

When valve installed "in line" connecting two distribution zones, the valve acts as a Pressure Sustaining Control Valve. When pressure in the upstream zone falls below the pilot setting, the valve modulates toward a closed position, sustaining pressure in the upstream zone.

When the valve is installed "in line" on the discharge of a pump, it acts as Backpressure Control Valve. When pump discharge pressure falls below the pilot setting, the valve modulates toward a closed position, increasing backpressure against the pump.
