Abstract
A snap-acting drain valve for draining a fluid system upon the occurrence of a predetermined temperature condition of the fluid. A spring-loaded valve is held closed against the spring force by a latching mechanism comprising a spring loaded latching lever engaging a shoulder on the valve stem, and a temperature sensitive actuator controlling movement of the latching lever. Upon occurrence of the predetermined fluid temperature, the actuator permits the latching lever to disengage from the valve stem shoulder, thereby releasing the valve which opens under spring force. The valve is non-modulating and will not close until manually reset even if the fluid temperature should increase to a level above the predetermined level.
