Beswick Engineering introduces its miniature 4-port and 6-port rotary selector valves with 1/4-28 UNF and 10-32 UNF threads. These valves offer bidirectional flow switching between four or six ports. They are designed with one central inlet at the bottom of the valve and four or six outlets on the perimeter of the valve body. Flow can also be directed from one of the outlet ports to the single inlet port. The valves are suitable for use with most liquids and gases (when a compatible O-ring material is selected). These valves are constructed of 303 stainless steel and seals are Teflon®, Buna-N, Silicone, Viton® and EPDM. The company’s team of degreed Application Engineers is ready to assist throughout the specification process.
