1. HS-TRVD-AD Adaptor for Drayton TRV3 Thermostatic Radiator Valves

    Leave a Comment

    The HS-TRVD-AD Adaptor allows any modern M30 threaded TRV head to be used with a Drayton TRV3 valve body. The inexpensive HS-TRVD-AD securely fits the TRV-3 whilst the broad high tensile stainless steel pin provides a perfect mechanical transmission of the automation force through to the TRV body pin.
