Manual Washing Machine  
Shutoff Valves
Size: 1⁄2" (15mm)
Series 2-M2 DuoCloz™ Manual Washing Machine Shutoff Valve 
is designed to control water flow from the hot and cold water 
supply piping to the flexible hoses feeding a washing machine.  
With a flip of its lever, you can turn the water on or off, thus 
protecting the washing machine parts and hoses from water 
damage, avoiding the potentially catastrophic results of a burst 
washing machine hose.* The Series 2-M2 Duo-Cloz™ can be 
installed in a more convenient spot than old boiler drain type 
2-M2-SC
hot and cold water shutoffs which are often installed in hard to 
reach places. This makes shutting off the water supply easier.  
The Series 2-M2’s ball-type design allows it to be opened to any 
position to throttle water flow and minimize harmful water hammer and banging pipes caused by fast closing washing machine 
solenoid valves.
Features
• Single lever turns off both cold and hot water supplies with the 
flick-of-the-finger.
Pressure — Temperature
Maximum Pressure: 150psi (10.3 bar)
Maximum Temperature: 180°F (82°C)
Dimensions — Weights
A
• Ball-type construction allows water to flow when 2-M2’s lever 
is placed in the down position and ceases water flow when 
lever is placed in the up position.
O-Rings
• Throttling feature minimizes the shock effect of quick closing 
washing machine solenoid valves. Lever can be set in any 
B
position to control water flow.
• When used properly, *prevents flooding due to burst  
washing machine hoses by relieving the hoses of constant 
supply pressure.
