The Willoughby PML2 and PSL2 Dual Temperature, Lead-free, Stainless Steel Pneumatic Valve Assemblies are water control valves for use with plumbing fixtures in security, commercial, and healthcare environments. They can be specified in either Metering (PML2) or Non-metering (PSL2) configurations.
Standard PML2 and PSL2 valve assemblies are made from components complying with NSF-61, and will typically come with selected stainless steel push buttons, pneumatic tubing and fittings, and associated plumbing connections. The dual temperature valve allows the user to select hot water or cold water, or combine both; however, the hot side of the valve must be supplied with tempered water to ensure proper operation and user safety (recommended with a max. operation temperature of 110° Fahrenheit). The valve assembly is designed for operational pressure between 35-70 psi (90 psi max.) and is supplied with an appropriate flex hose (1/2” F.P.T.) to connect to the operational water supply. Flex hose is supplied standard unless otherwise specified.
Both the PML2 and PSL2 valve assemblies can be supplied with a variety of optional features including: flow control, push buttons, thermostatic mixing valve, etc. A galvanized mounting plate is provided for secure anchoring of the valve assembly (anchoring hardware by others).
