Temperature Control Valves
In operation Walton Temperature Control Valves work continuously to maintain a constant system temperature by automatically proportioning fluid between the cooler and the bypass to maintain the required temperature. Movement of a rotor within the valve causes the necessary flow distribution to achieve this.
The following actuation types are available:
Self acting valves
Self acting (direct operated) valves incorporate a temperature sensor inside the valve, and operate independently of external power supplies.
Electrically operated valves
Electrically operated valves are powered by an external electric actuator, with control provided by a separate electronic control unit, and temperature sensing by resistance thermometer.
Pneumatically operated valves
Pneumatically operated valves are powered by an external pneumatic actuator, with control provided by a pneumatic controller with external temperature sensing.
Gas operated valves
Gas operated valves are designed to control refrigerant gas pressures – and hence the temperature of refrigerated or air-conditioned areas – in marine systems in which the condenser is cooled by sea water.
We are always willing to consider creating a customized solution to meet the needs of a client if our standard products are not suitable.
Our advanced computer aided design software and the flexible nature of the Walton valve design mean that this can often be a cost-effective approach.
