CONRADER SRV390-1/2-V-SS-150 Safety Valve Soft Seat 1/2 Inch 150 Psi Stainless Steel

Conrader SRV390-1/2-V-SS-150 safety valve is used in liquid pipelines, vessels and boilers to protect against overpressure of the fluid. This soft seat safety valve is used to prevent sudden pressure surges resulting in explosions, malfunctions and fire hazards.

Working Mechanism:

• When the pressure rises above the maximum allowable working pressure (MWAP) or the pressure for which the system is intended to operate, overpressure occurs.
• A safety valve opens when a certain pressure is reached; it opens partially at first, then completely to eliminate undesirable pressure from the system as rapidly as feasible.

Features:

• Conrader SRV390-1/2-V-SS-150 safety valve features stainless steel body and spring for resisting corrosion on exposed surfaces.
• It comes with Viton seals for resistance against chemicals and UV damage.
• This Conrader SRV390 valve comes with a set pressure range of 25 to 300 PSIG & flow factor of 1.55.
• It comes with nickel plating for wear resistance.

Standards and Approvals:

• ASME
• CRN

Frequently Asked Questions:

Q. How often should a Conrader SRV390-1/2-V-SS-150 valve be tested?

A. These safety valves should be tested periodically, ideally once a year. Additionally, testing frequently entails a risk that debris or other contaminants could enter the valve seat and cause leaks.

Q. What is the preset pressure setting of this safety valve?

A. 150 PSI.

Q. What is the operating temperature range of Conrader SRV390-1/2-V-SS-150 safety valve?

A. -65 to 400 degrees F.

Q. How can we install a safety valve?

A.

• It is essential to place the valve such that no condensate can build up on the disc of the safety valve's upstream side.
• This is normally done by installing the safety valve above the steam pipe.
• In case, the condensate will fill the connection to the safety valve, which is positioned below the steam pipe.
