Product Description

Self-operated Temperature Control Valve (ZZWP)

Summary:
Self-operated temperature control valve can work normally without power and the air source . It adopts the principle of thermal expansion of liquid and liquid incompressibility to control automaticly. Its nominal pressure is PN1.6; PN4.0; nominal diameter is 15-150mm; temperature range is 0 ~ 250 ºC. THer are various kinds of control valves to be choosed.

Working Principle:
Self-operated temperature control valve adopts the principle of incompressibility of temperature sensitive liquid to automatically adjust the temperature. It has two types: heating type and cooling type. When the temperature of the controlled medium increases, the control valve closes (heating type); when the temperature of the controlled medium increases, the control valve opens (cooling type).
