XDV Pneumatic valves play an important role in a pneumatic system. They determine how much air passes through and in which direction. This means that they can be used as control valves, but also as safety valves that shut off the air supply in dangerous situations or that depressurise the system. Every valve basically consists of three elements: Typically 2, 3 or 5 connections which are also called ports. The minimum of two ports provides power to the valve and work. A third port is used for exhausting the valve or actuator if necessary. If five ports are available, this is usually to control a double-acting cylinder. One port remains available for supply, two ports are used for working and two for exhausting. A port is nothing more than an opening with a thread into which a coupling can be inserted. Often a push-in coupling with which a direct hose connection can be made.

XDV Electric valves are high-end products in automatic valves. They can not only switch on and off, but also regulate the valve position. The stroke of electric actuator can be divided into two types: 90 degree angular stroke and straight stroke. The special requirements can also meet 180 degree, 270 degree and 360 degree full stroke. The electric actuator with angular stroke cooperates with the valve with angular stroke to realize the internal rotation of the valve to control the pipeline fluid opening and closing, while the electric actuator with straight stroke cooperates with the valve with the valve with straight stroke to realize the control of the pipeline fluid opening and closing by the action of the valve plate.

XDV Electro-hydraulic actuators are devices that operate a valve through pressurized hydraulic fluid, however, their main source of energy is solely electrical. The electrical power supplied is used to energise a motor that runs a hydraulic pump which then supplies the pressurized fluid to operate a hydraulic actuator which controls the valve. The complete system is self-contained, eliminating the need for a separate hydraulic power unit, simplifying system construction and improving safety and reliability. A self-contained electrohydraulic actuator can be used with linear or rotary valves, the need for its use will depend on the requirements of the application. These devices are ideal for operating valves that need large torques or thrusts, or where fail-safe systems or high operating speeds are required.

XDV actuators is designed to use pipeline gas as the motive power source. The gas is delivered to oil tanks that convert the gas into hydraulic pressure. This pressurised hydraulic oil is used to drive our industry recognised and proven scotch yoke quarter-turn or linear actuators. Using pressurised oil as the driving fluid provides powerful and smooth actuator control and isolates the cylinder from pipeline gas. This prevents contaminants from entering the hydraulic cylinder, eliminating corrosion and seal deterioration, and extending actuator life.
