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.

Compressor lubricating oil for Qatar oil refinery

A valve was required to control the temperature of lubricating oil on a compressor to be supplied to the Al Shahdeen oil refinery in Qatar.

Compressor lubricating oil for Qatar oil refineryThe customer’s specification called for a carbon steel valve body with a stainless steel operating mechanism. While the common grades of these materials fall within Walton’s standard product range, an unusual feature of the requirement was that more specialised grades of material were called for on certain parts of the valve. Our flexible product configurator system enabled us to quickly compile a build specification for the valve, and source appropriate materials.

A further requirement was that all materials used had to originate from specified geographic territories. Walton’s material traceability system enabled us to verify that this would be achieved.

This project illustrates that while Walton’s standard products can be configured in many ways to suit most needs, we are always willing to work with customers that have more specialised requirements.
