Data for 658VY
The 658VY is a 1/4" NPTF side ported, 3 position, spring centered, float center spool, pilot operated valve. The internal spool is shifted by 50 to 250 psi pilot air supplied to the 1/8" NPTF pilot port in each end cap of the valve. Valve components are stainless steel or brass.
Details
Pressure: 15 to 250 psi on the main body of the valve, 50 to 250 psi pilot air.
Vacuum: The five main ports can be operated on industrial vacuum to 28" Hg, based on a 30" barometer.
Temperature: -20°F to 250°F. Caution: If it is possible that the ambient temperature may fall below freezing, the medium must be moisture free to prevent internal damage or unpredictable behavior.
Mounting: The valve can be mounted in any orientation.
O-Rings: Viton.
Materials: stainless steel body, hard anodized aluminum spool, stainless steel end caps, brass spring centering block, composite gaskets, stainless steel fasteners.
Flow: 73.9 SCFM, 1.6 Cv
Repair Kit: ERKV-3.
3-Way or 5-Way: While this valve is basically 4-way, it can be used for 5-way service by using ports 2 or 4 as an inlet, or 3-way service by plugging the unused port 2 or 4.
Fluid Media: Soft seal models are made for air, vacuum, and gases compatible with component materials. They should not be used with liquids.
