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.

Service

Walton's temperature control valves are extremely durable and provide many years of reliable service with minimal maintenance requirements. Indeed, we know of valves that are still providing accurate temperature control after 20 years of service!

Sometimes, however, there are occasions when the plant on which the equipment is installed needs to be overhauled, and this may provide an opportunity to refurbish the temperature control valve. To this end, Walton offers a full repair and refurbishment service for life-extension of customers' Walton-supplied products. This also provides an opportunity to bring the valve up to our latest design specification.

The service entails return of the equipment to our factory where we will first carry out a detailed survey of the product’s condition to enable us to provide an accurate quotation for the work required. If this is acceptable an order is placed and the refurbishment work carried out to meet the customer's delivery requirements. Finally, Walton returns the refurbished valve(s) to the customer's premises.

  

Spares

It is inevitable that occasionally component parts within Walton products will need to be replaced during the course of their long lives.

As the supplier of the original temperature control equipment, Walton's spare parts are guaranteed to be genuine, quality-assured and meet all relevant technical standards. Where necessary, fitting instructions are provided.

Most commonly-required spare parts are available from stock. Limited quantities of less frequently required items are also usually available quickly: where this is not possible, a firm delivery date will be quoted at time of enquiry.

Contact us with details of your specific requirements at sales@waltonengineering.co.uk. It is helpful if you can supply the serial numbers of the products in question. For a temperature control valve, these are hard-stamped on the valve's front cover.
