Doc: CH-4401/02 Nov 2007

Air operated 2 way ASA150 stainless steel ball valve

Quick guide to the
CH-air A Type actuator standard features : Full bore 2 way 2 piece stainless steel ball valve, ends flanged PN16, designed for automation with integrally cast ISO5211 actuator mounting platform allowing direct mounting of actua- tors, fitted with CH-air ‘A’ type pneumatic actuator. Supplied assembled and dry bench function tested. Minimum of 80 psi (5.5 bar) air supply pressure to the actuator is required. 4401 With double acting actuator 4402 With spring return actuator Size range 1/2” to 6” (For PN16 flanged option, see 4101/2) Robust rack and pinion construction High accuracy machining of components ATEX Ex II 2 GD approved for use in hazardous areas CE Approved Guaranteed for 1,000,000 cycles Balanced air & spring strokes in spring return version Safe to dismantle for routine maintenance Compliant with all actuator standards
Valve Specifications: Applications: Water, low pressure steam, oil, air and most solvents and alkalis, subject to compatibility with wetted parts in contact with media. Actuators sized on a maximum differential pressure of 150 psi wet service, if the intended duty is above this differential, or dry (air or gas) call to check actuator sizing as a larger output actuator may be required. Maximum working temperature of valve & actuator assembly is +80C. If the intended duty is at a higher tem-perature than this, select Model 4411/ 4412 which has a mounting kit fitted between the valve and actuator which uses air cooling to dissipate the heat away from the actuator (maximum +130C). Accessories are easy to mount Hard anodised aluminium body ENP coated option (Extra cost) Teflon® coated option (Extra cost)
Accessories: Stainless steel version (Extra cost)
Position control: The standard on/ off function can be converted to modulating func- tion, using either a 3-15psi or 4-20mA control signal, by adding a pneumatic or electro-pneumatic positioner. See our YT range for details. Position Confirmation: Remote end of travel confirma-tion can be provided by adding a top mounted limit switch box. A variety of switch options and housings are available See our LSB range for details. Solenoid control: This provides electrical control of the valve. The air is con- stantly supplied to the solenoid which in turn controls the air to and from the actuator. The solenoid direct mounts to the actuator using the actuator’s Namur connection.
