Doc: CH-2111/01 Nov 2007

Air operated 2 way stainless steel ball valve with kit

Quick guide to the
CH-air A Type actuator standard features : Full bore 2 way 3 piece stainless steel ball valve, ends BSP, designed for automation with integrally cast ISO5211 actua- tor mounting platform allowing direct mounting of actua- tors, fitted via stainless mounting kit with CH-air ‘A’ type pneumatic 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
2111 With double acting actuator 2112 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
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 +150C. If the intended duty is at a higher tem-perature than this, contact us to discuss options. Compliant with all actuator standards
Body CF8M Cast 316SS Ball CF8M Cast 316SS Seats RTFE 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: 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.
