1 2 GENERALVALVECOMPANY Resilient seal before seal after RETRACTION & COMPRESSIONASSURES NO-LEAK STREAM SEPARATION ANDLONGER SEAL LIFEG eneral's Four-Way does not rely on line pressure orexternal hydraulic pressure for positive sealing. Theseating elements, or slips, move perpendicularly againstthe face of the ports. The seals themselves are highlyresilient elastomers which are either bonded ormechanically retained in the of the slips,away from the body prior to cycling prevents frictionand abrasion which can damage seals.

2 There is neverany sliding or rubbing of the seals against the valve bodyor ports. Metal-to-metal secondary seating preventsovercompression of the resilient primary OPERATINGAND DOWNTIMECOSTSB ecause the seatingsegments are mountedvia dove-tailed connec-tions to the plug, theymay be removed fromthe top or bottomandexamined without havingto take the valve from theline or disturb theactuator. This addedflexibility allows the valveto be installed upsidedown for easy access toactuator and CYCLINGFast and easy operation by hand or automaticallywith electric motor or hydraulic actuators is cycling torque permits use of smaller and lessexpensive power standard gear operated Four-Way is NOT selflocking, therefore it is recommended that all manuallyoperated Four-Way Diverter valves be equipped with alatching device to maintain seating position when thevalve is unattended.

As the seals trap fluid betweenthem and volumetric space increases the body pressuregauge would once again indicate less than line :Valve position is quickly identified with a top-mounted flag. Position-indicator switches are avail-ablefor remote locations.

5 (see page 8)AUTOMATIC PRESSURE GAUGE FOR OUICK CHECK OF SEAL INTEGRITYG eneral's Four-Way Diverter uses the reliable pressuregauge method of checking for positive sealing to assuremetering accuracy. The gauge automatically indicates sealcondition each time the valve is seated during proving, evenin low differential operating pressure gauge connects to the body cavitybetween the valve slips. As the slips expand in the divertedposition, the resilient seals contact the valve body, trappingthe fluid between them. Further expan-sion of the slipsduring valve seating compresses the seals further.

6 Theresulting increase in volumetric space between the slips,without an increase in the amount of fluid, will cause a dropin leakage through either seal permits additional fluidto enter the body cavity, causing an immediate increase incavity pressure back to line pressure. Even the mostminimal fluid leak will register on the gauge pressure switch may be used to supplement the gaugemethod as an option (see page 9).Seated in"R/L-Close - CCW"Position (Top View)Neutral - FullyUnseated PositionSeated in"J/R-Open - CW"Position4 GENERALVALVECOMPANYVALVE DIMENSIONS & WEIGHTSGEAR OPERATEDDETGJKFHCABStd.
