Doc: CH-1111/02 Nov 2007

Air operated 2 way brass ball valve with kit

Quick guide to the
CH-air A Type actuator standard features : Full bore 2 way nickel plated brass ball valve, designed for automation with integrally cast ISO5211 actuator mounting platform, fitted via stainless steel mounting kit with CH-air ’A’ type pneumatic actuator. Supplied assembled and dry bench function tested. Minimum of 80 psi (5.5 bar) air sup-ply pressure to the actuator is required. Robust rack and pinion construction High accuracy machining of components
1111 With double acting actuator 1112 With spring return actuator ATEX Ex II 2 GD approved for use in hazardous areas Size range from 1/2” to 2”. Valves are WRAS approved for use on potable water. 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, oil and most non-corrosive media, 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 assembly is +130C. If the intended duty is at a higher temperature than this, select a stainless steel valve - contact us for information. Compliant with all actuator standards
Body Nickel plated brass Ball Nickel plated brass Seats PTFE Pressure rating 40 bar Valve temp limits -20 to +150°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.
