Bronze Pop-Safety Valves

These valves meet ASME Code Section I for use with steam power boilers requiring pressure relief above 15 psi. They spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. For remote discharge, attach a drain line to the threaded relief port. Valves have a durable bronze body for a long service life.

EPR rubber seals provide better leak protection than brass seals.

Swivel test levers rotate 360° around the valve for use in areas with limited clearance.

ASME-Code Fast-Acting Pressure-Relief Valves for Low-Pressure Steam

For Use With: Steam
Specifications Met: ASME BPVC.IV
Max. Temperature: 250° F

For use with low-pressure steam-heating boilers requiring pressure relief at 15 psi, these valves meet ASME Code Section IV. All spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. Body is bronze for durability and a long service life.

Vented relief ports exhaust discharge directly.

Threaded relief ports can be attached to a drain line for remote discharge.

Fast-Acting Pressure-Relief Valves for Ultra-Low-Pressure Steam

For Use With: Steam
Max. Temperature: 250° F

Choose these valves for small steam-heating boilers requiring pressure relief between 5 psi and 12 psi. They spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. All have a bronze body for durability and a long service life.

Vented relief ports exhaust discharge directly.

Threaded relief ports can be attached to a drain line for remote discharge.

Valve With Test Lever

Valve With Swivel Test Lever

For Use With: Air, Inert Gas
Specifications Met: ASME BPVC.VIII
Temperature Range: See table

Unlike valves that release discharge directly, these have a threaded relief port to direct discharge away from your work environment. They spring fully open at the set pressure and remain fully open until the system pressure is restored below the set pressure. All meet ASME Code Section VIII for use with air and inert gas pressure vessels. Body is bronze for durability and a long service life.

Fluoroelastomer seals provide better leak protection than brass or 316 stainless steel seals.

Swivel test levers rotate 360° around the valve for use in areas with limited clearance.

Fast-Acting Temperature- and Pressure-Relief Valves for Hot Water

Female × Female

Male × Female

Male × Female With Extended Body

For Use With: Water
Specifications Met:
Pipe size of 3/4-2: ASME BPVC.IV
Pipe size of 1/2-2: CSA Certified
Max. Temperature: 210° F

Also known as T & P valves, these open when water temperature reaches 210° F or at the set pressure. They are commonly used with water heaters and storage tanks. All spring fully open at a water temperature of 210° F or the set pressure and remain open until the system is restored below the set point. For remote discharge, valves have a threaded relief port to attach a drain line. Body is bronze for durability and a long service life.

Valves with 3/4 to 2 pipe size meet ASME Code Section IV for hot water.

Valves with an extended body are designed for installation through thick insulation.
