The Series-22 Quarter-Turn Dia-Cam valve is a high flow capacity pinch valve, designed for hard-to handle fluids, especially slurries. The valve interior consists of a fabric reinforced elastomeric or PTFE-lined Diaphragm Spool... the only wetted component of the valve. Two opposing gear-driven cams, contained in a flanged split vinylester-fiberglass body, act on the Diaphragm Spool, providing flow control over the entire 90 degrees of valve stem travel. The valve exhibits negligible pressure drop in the open position and bubble-tight closure even around solids in the closed position. Where solids in the slurry make operation of other types of valves such as ball, plug and butterfly valves extremely problematic, the Series-22 Dia-Cam valve is ideally suited for slurries since there are no "dead zones" in the valve internals.
The valve ID mates to Schedule 40 piping systems and installs without flange gaskets. The valve is utilized in either ON-OFF or FLOW CONTROL applications.
Manual operation of the valve is accomplished with a 6-position notched detent plate and spring-loaded lever assembly. Automated operation is achieved by specifying a Clark RE series electric quarter-turn actuator. Pneumatic actuators are available on request.
Maximum working pressure for all sizes is 125 psig. Operating temperature is -40 to 275°F, depending on the elastomer system used in the valve. For throttling applications, proper valve sizing involves determining the Cv required, taking into consideration fluid viscosity, pipeline size and cavitation potential. Consult Factory for sizing verification.

On-Off. Tri-State & Modulating Control Model RE electric/electronic actuators are ideal for Series 22 valve applications. The actuators are available with torque ratings from 150 in-lbs to 10,200 in-lbs. They incorporate current limiting as a means of protecting the actuator for over-torque situations and do not depend on torque switches or thermal overload sensing. The current limiting feature activates a light (and an optional relay) upon exceeding the current limit set to allow for easy field diagnostics. All actuators accept 24 VAC or VDC power and 120 or 220 VAC with the addition of a transformer. All actuators have field adjustable speed control as a standard feature. Actuators are designed for temperatures ranging from -40 °F to 150 °F (-40°C to 65 °C). For temperatures below 32°F (0°C), outdoor applications, high humidity or wet locations, the actuators can be supplied with an electric heater and thermostat. All actuators have a solid state braking system, which works with or without power, (rated to 1-1/4 times the torque rating of the actuator). All units are equipped with a manual override, which will allow the actuator to be rotated in the clockwise or counter-clockwise direction. Optional solid cast aluminum override handwheels are available (spoked handwheels are not acceptable due to safety issues). The actuator housing is a high strength aluminum casting with an exterior grade polyurethane enamel coating for excellent wear, corrosion, impact and UV resistance. The actuators are NEMA 4/4X type minimum. All cover fasteners are stainless steel. All actuators have a position indicator with the angle of rotation clearly marked. All actuators used in outdoor applications have white covers to lessen the solar heat load. Model RE is capable of accepting 4-20 mA with 250 Ohms impedance, 0-10 VDC or 2-10 VDC signals. Input signal isolation is provided to isolate the input signal from the actuator power so that the signal and power can come from different sources, without the need for exterior isolation modules.

Torque Maximizer for 3" pinch valves The Torque Maximizer permits Model RE actuators to operate at required torques up to 10,200 in-lbs. It also allows the actuator to be mounted in applications with space or location limitations. The Torque Maximizer provides added gear reduction between the actuator and the valve, thereby increasing the torque of the actuator. This product is 85% efficient in transferring the torque from the input to output drive shaft. This unit bolts directly onto the base of the RE actuator, then the combined actuator/gear operator unit is mounted to the valve. |
