Emergency Relief Vent

The L22E Emergency Relief Vents are designed to provide superior sealing and industry leading high flow rates. When properly sized, the high flow capacity will prevent the tank from damage in an emergency case.

Pipe-Away

Model L1220A is used for pressure and vacuum relief where vapors must be piped away. Escaping vapors are piped away through a flanged outlet connection. This helps to provide increased fire protection and safety.

Pressure Relief Valve

Model L2300A is designed for emergency relief capacity above that supplied by a standard operating valve used on tanks, piping, and low pressure vessels. Emergency relief valves provide relief from excessive internal pressures which may cause tank damage.

Vent to Atmosphere

Model L1200A is designed to protect your tank from damage created by overpressure or excessive vacuum. Costly product evaporation losses due to normal tank "breathing" are greatly reduced. Because the Model L1200A retains toxic vapors, atmospheric contamination is minimized. This helps to provide increased fire protection and safety.

KPRV Chemical Feed Pump Relief Valves

KENCO KBPV Back Pressure Valves are two-way relief valves designed to keep a constant pressure in the discharge lines of a chemical feed pump system. Constant pressure on the discharge side of the chemical feed (metering) pump prevents siphoning, ensuring proper operation of the pump and an accurate chemical dosage rate.
