DISCOVER WHAT THE MINIDISC® DESIGN MEANS

The superb simplicity of disc meeting shaft at 45° means the seat is unpierced, for the purest of product integrity. The 180° rotation angles the disc cleanly through the product flow so the valve opens without resistance and stays in place. Half a turn of the valve handle provides quick, positive, leak-free shutoff. An "OPEN - CLOSE" mylar label indicates the status at a glance. A simple twist of the accessory lock-handle transforms the   MINIDISC®   into a regulating valve, locking firmly into any desired position.

The   MINIDISC®   is truly easy to maintain. Made entirely of stainless steel, type 304 or 316, it dismantles without tools, in seconds, simply by opening the standard heavy-duty clamp. Only three low-cost elements ever need replacement: the seat and two stem "O" rings. Changing them is a snap. The two "O" rings on the disc shaft prevent the entrance of the product into the stem housing. Two leak detector holes alert operator of worn "O" rings.

To insure a wide variety of applications, diverse gasket materials are offered. The seat is available in Teflon, buna, silicone, EPDM and Viton® (surcharge). The standard "O" rings are buna or Viton®. Other elastomers, EPDM and silicone, are available on request. Innovative, yet time-tested, long lasting, sanitary and fairly priced, the   MINIDISC® valve boasts a proven record in the field.

MAXIMUM IN-LINE FLOW PRESSURE  
Valve Size 1 1/2", 2", 2 1/2"............................120 psi  
Valve Size 3", 4", 6".........................................80 psi

NOTE: The   MINIDISC®   valve is installed with the product flowing against the flat disc (see arrow). If the product flow is reversed, the pressure resistance will be reduced.

AIR ACTUATED MINIDISC VALVE

The all stainless steel actuator for the   MINIDISC®   mounts quickly on the stem housing of the valve. A set screw allows removal in seconds. The disc stem of the air-actuated valve terminates in a square shaft. This fits into a brass coupling which, in turn, connects to the pinion gear. Two brass racks govern the 180° rotation as the air or springs control the two pistons.

The actuator is available air-to-open/ air-to-close or air-to-open/ spring-to-close (fail-safe). If the air supply should fail, the valve can be operated manually by turning the exposed square ended gear shaft. A double-acting microswitch or microswitch/solenoid valve, in a housing, is offered as an accessory. It mounts easily on top of either actuator.

Efficient, rugged and reliable, the double-acting rack and pinion actuator is the perfect compliment to the   MINIDISC®   valve.

Also Available:   Adjustable actuator model.

MICROSWITCH UNIT

The stainless steel unit can be installed on either actuator. Air-to-Air or Air-to-Spring. The cam is bolted into the gear shaft and rotates with the disc, triggering one switch valve when the valve is fully open, the other when fully closed. ALSO AVAILABLE WITH SOLENOID VALVE.

LOCKING HANDLE

Lock Washer holds valve in position when threaded into stem.

Spring Loaded Extra Security Locking Handle

Using the extended stem of an air actuated style disc and stem, the spring loaded handle hugs the locking pins on the stem shaft. The top button is drilled to permit metal give for yet additional security.
