Descripción completa del producto

The PV-20 Series is a PTFE fluoropolymer air-operated diaphragm valve used for flow control of abrasive slurry media and aggressive fluids in semiconductor and clean-area applications. The valve’s flow path design produces minimal pressure drop, which allows for lower pressure requirements upstream and improved fluid flow dynamics. It is available in 2-way and 3-way configurations, along with three orifice sizes (1/4 inch, 1/2 inch, and 1 inch). Port sizes range from 1/4 to 1-1/4 inches, and can be supplied with Parflare, Pargrip or Nippon Pillar S300 end connections.

The body of the PV-20 Series slurry valve is made from virgin 100% ultra-high purity PTFE for superior chemical resistance. This, coupled with a one-piece modified PTFE diaphragm, affords the valve with excellent flexibility and maximum cycle at pressures up to 100 psig. The valve itself is also highly compact, which enables operators to conserve critical cleanroom and sub-fab space.

The angled and rounded flow path of the PV-20 Series, plus an open and swept bowl shape around its diaphragm, minimizes turbulence and eliminates sharp angles that can cause fluid shear. This reduces particle entrapment and provides increased protection against corrosion.

Overall, the valve’s design makes it particularly suitable for handling abrasive and corrosive slurry fluids, such as such those found in the CMP (chemical-mechanical planarization or chemical-mechanical polishing) processes employed in semiconductor fabrication. The PV-20 Series is also suitable for a wide range of other clean-area processing and analytical applications, such as controlling the flow of acids, chemicals and DI water.
