Realm Corner TRV & Lockshield Set Chrome

Made to a high quality the wheel-head and lock-shield radiator valves are constructed from brass and have a heavy smooth polished finish and features variable pitch adjustable couplers.

We recommend all TRV's are installed on the flow rather than the return pipework of a radiator. When used in conjunction with a system automatic bypass valve this thermostatic valve can be installed on either the flow or return in any orientation. System automatic bypass valves are a specific building regulation requirement for all new installations and boiler upgrades. All bi-directional TRV's from any manufacturer require the bypass valve to function correctly and thus avoid radiator hammer.
