Safety Relief Valves

Increasing reliability and service life, reducing costs and downtime

A full range of repair, overhaul, testing and calibration services

Guarding against a dangerous build-up of pressure, safety relief valves play a critical role and KVS’s repair and overhaul services are designed to ensure they’re always ready to respond.

With regular inspection, testing and maintenance, safety relief valves can have a service life of many decades. Typically, we recommend that overhauls take place every two years or whenever a valve has activated.

Safety pressure relief valves operate by opening or lifting at a predetermined set pressure. This relieves pressure by releasing process media until system pressure drops to normal operating level, but activation can lead to debris accumulation and damage.

KVS’s relief valve repair and overhaul solutions support customers throughout the UK and across multiple industrial sectors, including energy from waste, food and beverage, oil and gas, power, refining, and chemical.
