Direct operated valves

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.

Walton Engineering has been designing and manufacturing temperature control systems for more than 60 years. During this time our systems have gained an enviable reputation for reliability, robust operation and minimal maintenance requirements, based on expert design and proven engineering skills.

Our systems are used wherever fluid temperature control is vital – principally in marine, industrial, power generation and rail applications. These include:

  • Fresh water for diesel engine jacket and auxiliary cooling systems
  • Lubricating oil for bearings, gearboxes, pumps and compressors
  • Hydraulic oil for controllable-pitch propellers
  • Sea water for chillers, fresh water/sea water heat exchangers and refrigerant gas pressure control

The accurate temperature control provided by Walton systems is vital and plays a significant part in reducing both operating and maintenance costs.

Walton systems are recommended by leading diesel engine, steam and gas turbine manufacturers.
