At SHSUOTE Valve, technology improvement and innovation are our core advantages. Since established, we have been focusing on developing new products, improving product quality, and serving customers. water pressure relief valve If you are interested in our new product water pressure relief valve and others, welcome you to contact us. is a manufacturer with strong strength and rich production experience. It has many years of water pressure relief valve manufacturing experience. The water pressure relief valve produced is fine in workmanship, excellent in performance, affordable, and reliable in quality. Compared with other similar products, the comprehensive cost performance is higher .
▶OPERATING DATA
Pressure Relief Feature
Pressure relief control (3)is a normally closed control that responds to main valve inlet pressure changes.An increase in inlet pressure tends to open control (3)and a decrease in inlet pressure tends to close control (3).This causes main valve cover pressure to vary and the main valve modulates (opens and closes)maintaining a relatively constant pressure at the main valve inlet.When inlet pressure is lower than the set point of control (3),control (3)closes.This pressurizes the main valve cover chamber and the main valve closes.Pressure relief control (3)adjustment:Turn the adjusting screw clockwise to increase the setting.
▶Closing Speed Control
Needle valve (2)controls the closing speed of the main valve.Turn the adjusting stem clockwise to make the main valve close slower.Do not close valve (2)completely or the main valve will not close.(Suggested initial setting of needle valve is 1/4 to 1/2 turn open.]
▶Optional Features
(B)-Isolation Valves:
Isolation Valves(B1)and (B2)are used to isolate the pilot system from main line pressure.These valves must be open during normal operation.
(D)-Check Valves with Isolation Valves:
When outlet pressure is higher than inlet pressure,check valve(D2)opens and check valve (D1)closes.This directs the higher outlet pressure into the main valve cover and the main valve closes.
(F)-Remote Pilot Sensing:
Pilot sensing pressure is obtained from a point upstream of the main valve inlet.(Pilot sensing pressure is obtained from the main valve inlet if suffix (F)is not specified.)
(H)-Atmospheric Drain:
Pilot system drain line is discharged to atmosphere.(Pilot system drain line is connected to the main valve outlet boss if suffix(H) is not specified.
(P)-Pressure Gauge:
Pressure gauges (P1),(P2),and (P3)provide pressure reading in the inlet,outlet,and cover connections.
(S)-Opening Speed Control:
Flow control (S)controls the opening speed of the main valve.Turn the adjusting stem clockwise to make the main valve open slower.
(V)-Valve Position Indicator:
Valve position indicator (V)displays a visual position of the main valve stem.
