Fluid power valves

Fluid power valves

Minimatic(R)shuttle valves from Clippard Instrument Laboratory have threaded inlet ports and integral hose barb fittings. The valves are available with 1/16- or 1/8-inch ID hose fittings, male or female threaded ports, or combinations of all four options. The valves have poppet-type shuttles that allow flow from one inlet to the outlet while blocking the other inlet. A variety of inlet and outlet porting options eliminates adapter fittings and potential leak points.

The Magna-Cycle 4-way directional control valve from Lexair Inc. automatically reverses the direction of a pneumatic cylinder when it meets an obstruction or senses a pre-set cylinder load. The valve eliminates delays in automated material handling operations. Built with brass and has a stainless-steel spool, the pneumatic valve is sub-plate mounted, available with 1/4- to 1/2-inch NPT or SAE port sizes, and has a pressure rating of 150 psi.

Norgren's V44 has a spool and sleeve construction specifically designed for applications exceeding 100 million cycles. It accommodates pressures up to 230 psi. The spool and sleeve are coated with Nituff(TM). The V45 has a thin lip spool, is rated for 50 million cycles, and accommodates pressures up to 150 psi. Both V44 and V45 are mini-ISO valves and available in the company's e-commerce web store at www.norgren.com.

The HE-U is a new lockout valve for compressed air systems from Festo Corp. that complies with OSHA standards for control of hazardous energy under title 29 CFR 1910.147. The in-line valve interrupts compressed air supply to pneumatic machinery during maintenance and allows venting of residual downstream pressure.
