Doc: CH-2401/02 Nov 2007

Air operated heavy duty stainless steel ball valve

Quick guide to the
CH-air A Type actuator standard features : 2 way reduced bore heavy duty 3 piece stainless steel ball valve, ends BSP, designed for automation with integrally cast ISO5211 actuator mounting platform allowing direct mounting of actuators, fitted with CH-air ‘A’ type pneu- matic actuator. Supplied assembled and dry bench func- tion tested. A minimum of 80 psi (5.5 bar) air supply pres-sure to the actuator is required. Robust rack and pinion construction High accuracy machining of components ATEX Ex II 2 GD approved for use in hazardous areas
2401 With double acting actuator 2402 With spring return actuator Size range 1/4” to 4” (Butt & socket weld end options) 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 10 bar 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 +70C. If the intended duty is at a higher tem-perature than this, select Model 2411/ 2412 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). Body CF8M Cast 316SS Ball CF8M Cast 316SS Seats Carbon filled PTFE Pressure rating UTI 2” 64 bar, rest 50 bar Valve temp limits -20 to +200°C Actuator temp limits -20 to + 70°C Accessories are easy to mount Hard anodised aluminium body ENP coated option (Extra cost)
Accessories: 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. 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. Teflon® coated option (Extra cost) Stainless steel version (Extra cost)
