You are bidding on a New Parker Veriflo 944 Series Stainless High Purity Air Operated High Pressure Diaphragm Valve, No. 944PLVVCRMF. PLEASE NOTE - Each bid is for ONE Valve.
The 944 is an The valve cross section on the opposite page illustrates the minimal number of wetted components of this unique design. The only moving part in the wetted area is the diaphragm itself. The heart of the 944 is the patented compression member which uniformly loads the PCTFE seat effecting a static seal without the need for threads or crimping and allowing for field replacement. The dynamic seal occurs at the top of the seat which extends approximately .008 inches above the compression member. The valve is closed when the “button” at the end of the piston is compressed against the diaphragm, causing it to move downward and seal against the seat. The compression member serves also as a positive stop for the diaphragm. When the diaphragm meets the stop, the PCTFE is still well within its elastic limit. The diaphragm is sealed metal-to-metal to the body and is the only seal to atmosphere other than the inlet and outlet connections. The diaphragm of the 944 is designed with an upward bias which enables the valve to be used with either an upstream or downstream vacuum. I fully guarantee these new Valves. Shipping in the Continental US is $6.90 - I have very competitive rates for our always welcomed International bidders. Additional valve configurations are available - see my other auctions.
