Catalog excerpts

Solenoid pilot valves are customarily used to operatepneumatic/hydraulic actuators,acting upon electrical signals to admit and exhaust supply pressure to the actuator.Four-way pilot valves are generally used with double-acting actuators,while three-way pilot valves are used on spring-return and spring-diaphragm models.Metso Automation maintains a complete stock ofsolenoid pilot valves for its line of pneumatic/hydraulicactuators and can recommend solenoid valves for specialserviceson an application basis.When pilot valves are ordered with actuators,they areassembled and tested before shipment from the factory. Solenoid pilot valves are normally mounted on double- acting actuators to provide for valve closure when de-energized.If reverse operation is required,the pilot valve will be mounted on the actuator with the supply connections reversed.Most solenoid pilot valves are supplied from stockwith standard enclosures for 115-volt 60-Hz AC service with a Class F coil.Pilot valves for other services,such as 230 VAC,480 VAC,or direct current,as well as valves with other coils,such as high temperature,are available on application.Enclosure ratings are given in the tables on page 2 of this Bulletin.The tables on page 2 list the recommended solenoidpilot valves for each Jamesbury actuator.Please note that the solenoid pilot valves shown are sized to provide the typical operating speeds cited in our individual catalog bulletins.These generally range from 1 second on the smaller actuators,up to 15 seconds on the larger ones.Other solenoid pilot valves,along with a variety of accessories such as quick exhaust valves and speed controls,are available when different speeds are required.Manual operators are also available for most models.Please consult the factory for further information on these options. > Bulletin A160-1Issue 3/2007 VPVL with Solenoid Specific actuator information can be found in the following Bulletins:Series B Piston ActuatorsA107-1Quadra-Powr X Spring-Diaphragm ActuatorsA110-4Valv-Powrή VPVL Mod CA111-3 Valv-Powr Stainless SteelA111-4 > To order a solenoid valve,simply choose the appropri-ate model from the tables on page 2 and specify the required voltage as shown in the example below: EX AMPLE: A standard solenoid valve with a NEMA 4enclosure for a QPX2 Quadra-Powr Xactuator would be specified as follows: 8320G182 (115V 60 Hz AC) >
