Relief Valve Manufacturers

A relief valve is a valve designed to provide protection from over-pressure in steam, gas, air and liquid lines. The valve "lets off steam" when safe pressures are exceeded, then closes again when pressure drops to a preset level.

TOMCO low cost, preset, pressure relief valves are thoroughly engineered and precision manufactured to protect against equipment damage or personnel injury that may result from dangerous pressure build-ups. A time-saving, money-saving feature of TOMCO relief valves is that their threads are "pretaped" with teflon tape to assure leak-proof installation. The first 1 1/2 threads are teflon-free to eliminate potential for tape shredding into, and contaminating, the vessel interior.
