Pilot-operated, three port, two position slide valve with a spring-return action
Special high pressure seals prevent leakage
Optional special seals for use as a selector
NACE Standard MR-01-75 compliance


Slide valves Type 3160 (normally closed) and 3165 (normally open) are manifold mounted, pilot-operated, three port, two position valves with a spring-return action. A major feature of the valve design is elimination of the continuous internal leakage which is characteristic of conventional lapped-face spool valves. The valves each incorporate special high pressure seals which prevent leakage and so render the valves suitable for use with many fluid media.

The valve slide (which can be supplied either normally closed or normally open) has a 'block before bleed' action. In a normally closed valve, for example, this means that the tank port is isolated before pressure and service ports are interconnected.

Slide valves Type 3163/3167 are as described for Types 3160/3165, but with special seals fitted to enable the valve to be used as a selector. For Type 3163 the pressure at Port 4 must always be greater than the pressure at Port 5. These port numbers are reversed for Type 3167 for which the pressure at Port 5 must always be greater than the pressure at Port 4.

Materials

Predominantly 316 stainess steel and CA104 aluminium bronze with seals of fluoroelastomers and PTFE materials, ensure high corrosion resistance and comply with NACE Standard MR-01-75 (latest revision as applicable).
