PSI Model 770 Ball Check Valve - Full Specifications

Prevention of Backflow

• PSI Model 770 Ball Check Valve prevents reverse flow in highly corrosive or ultra pure processes and its reliable design eliminates the need for expensive lined valves, actuators and an outside power source.

Simple Operation

• During normal flow, PSI Model 770 Ball Check Valve allows fluids to flow with minimal pressure drop and its thick plastic liner constructions resist corrosion and potential permeation.

Versatile Installation

• PSI Model 770 Ball Check Valve can be installed at any angle within a piping system and its short face-to-face dimension allows installation where space is tight.

Variety of Sizes and Liner Materials

• PSI Model 770 Ball Check Valves are available with PFA, PVDF and PPL plastic liners.  The valve body is constructed of cast ductile iron wit zinc-plated steel studs and nuts with 150# ANSI bolt pattern.

PSI Model 760 Sampling Valve - Full Specifications

• PSI Model 760 Sampling Valve assembly is designed for use in lined pipe systems for withdrawal of samples of fluid from a process line without disturbing normal process flow.

• The thick PFA liner construction is suitable for corrosion resistance, chemical resistance, adhesion prevention of impurities and potential permeation.

• Sampling plug is made of stainless steel lined and covered with PTFE to assure excellent high temperature corrosion resistance to virtually all chemicals. See Chemical Resistance Guide for more information.
