Pressure relief valves

WORKS WELL UNDER PRESSURE

Pressure relief valves are a critical component of fuel, hydraulic, and pneumatic systems in many industries. These valves can serve one of three functions—safety relief, pressure regulation, or protection against thermal expansion. The Lee Company offers a wide range of pressure relief valve configurations designed to ensure that we can offer the right solution for a specific application, helping to guarantee the safety and reliability of your product.

• Safety relief valves are designed to be fast-acting components that protect systems with the potential for sudden pressure spikes.
• Pressure-regulating relief valves are intended to operate more continuously with stable performance throughout the operating pressure range.
• Thermal relief valves are designed to relieve small volumes of fluid to protect against thermal expansion.
• Zero leak relief valves incorporate an elastomeric or polymeric seal for a zero-leak design.
