Fire Protection Pressure Reducing/Relief

600 Series  PR-Pressure Reducing Valve

Product Description

Armaş “PR” model pressure reducer control valve is the hydraulic control valve which reduces high upstream pressure value into desired lower pressure value by means of built-in pressure reducing pilot valves. Pressure reducer control valve controls downstream pressure value continuously and maintains it constant without being affected from flow rate and upstream pressure values. When no flow exists in the system, it is closer by itself automatically. When valve upstream pressure value decreases below adjusted downstream pressure value, it is opened fully by itself.

The valve will be direct diaphragm closing automatic hydraulic control valve which works with line pressure. No wearable parts such as stem, bearing and seat exist in main valve body. The valve position will be controlled by a hand operated selector valve.

Valve size same as main line or one size smaller. Maximum flow speed for continuous operation 5.5 m/sec (18 ft/sec)

Please submit following information to our sales department while ordering.
Maximum flow rate : m³/h
Maximum network/line pressure : bar
Main line size : mm
Valve connection type : ---
Maximum upstream pressure : bar
Minimum upstream pressure : bar
Desired downstream pressure : bar

3-way pilots are recommended to use at the application which has very close values between upstream and set pressure because of 3-way pilots provide less head loss.

 

Armaş Pressure Reducing Valves reduce pressure to setted downstream pressure value without affecting upstream pressure value at pressure chambers and supplying lines.
