Abstract
A water or other hydraulic system is protected by a thermostatic drain valve having a bimetal disc arranged with a three port cavity and a specially designed and compliantly sealed valve core so that the spring action of the disc acting together with the pressure of the fluid in the system constitutes the only power required to operate the valve.
