1. SERIES 2600 / 2633 Miniflex Installation, Operation, and Maintenance Manual Red Valve’s Series 2600 pinch valve and Series 2633 small diameter inline check valve are the simplest valves available to industry. They have only four parts and require little or no maintenance. These valves are designed with threaded end connections for easy installation and removal on small lines up to 3” in diameter. A spare replacement sleeve should be ordered when the valve is placed in service. NOTE: 2” and 3” PVC Series 2600’s may have hose clamps on the body of the valve. These clamps must be loosened when removing the sleeve. IMPORTANT Please take a moment to review this manual. Before performing any maintenance on the valve be sure that the pipeline has been depressurized. The improper installation or use of this product may result in personal injury, product failure, or reduced product life.

PRESSURE REGULATORS To avoid over-pressurizing the valve when closing, a pressure regulator should be installed. Pressure in ex - cess of 50 psi above pipeline pressure can tear the rub - ber at the flange. Higher pressures require the sleeves to be reinforced with fiberglass short threads. INSPECTION OF PRODUCT INSTALLATION Before installing, be sure the pipe threads are clean. A sealing material such as pipe dope can be used. Direction of flow is indicated on the 2633. Be sure that it is in the proper orientation before installing. FLOW 1. INSTALLING VALVE Use a wrench to tighten the valve by turning the end caps. Turning the body can damage the rubber inside. Once installed, if a small gap exists between the body and end cap, do not tighten further. This can twist the rubber flange inside and cause damage. Gap Gap 2. AIR SUPPLY PORT Air supply is connected to the 1/4” NPT port. This port is normally plugged on the 2633, but can be used as a drain or piped as a flush port. Use the chart below to determine the correct air pressure needed to close the 2600.

Make sure that the ridge on the rubber flange prop - erly fits into the groove in the seat by firmly pressing into place around the entire flange. 4. REINSTALL END CAPS To reinstall the end caps, lubricate the exposed rubber flange and tighten the end cap until snug. Do not over - tighten or the rubber flange may twist or tear. Caps will not bottom out on the valve body. 1. REMOVE VALVE Remove the valve from the pipeline using a wrench to turn the end caps. Do not grip the valve body! A spare replacement sleeve should be placed on order when this valve is placed in service. 2. REMOVE SLEEVE 2600: Unscrew both end caps from the body. Pry one side of either rubber flange out of its seat with a dull blade or screwdriver. Fold this edge over into the center of the sleeve and push the flange fully through the seat. Pull the sleeve out of the body. 2633: Unscrew the end cap on the inlet side of the valve. Pry one side of the rubber flange up using a screwdriver or dull blade and pull up to remove the duckbill sleeve from the valve body. The other rubber seal will only need to be changed if seriously worn. 3. REPLACE SLEEVE 2600: Lubricate the new sleeve with soapy water.
