The valves are designed for applications that require needle-free intermittent injection, aspiration, or infusion of fluids. They are available in Y and in-line configurations. Relief valves Miniature plastic relief valves are preset to spring pressures between 0.25 and 10 psi. S. Wadsworth, Ste. 315, Lakewood, CO 80232.
Servo valves Servo valves provide precise proportional control of fluid pressure and flow.
The valves combine a torque motor with a frictionless nozzle flapper, shear orifice, or jet pipe valve. The input signal can be either voltage or current, and the output is a precisely controlled stepless flow rate or pressure. The valves are suitable for use in piloting larger valves, providing servo control of actuators, and in fluid pressure and flow control applications. The valve consumes 500 mW maximum power and has a 200,000,000-cycle life. Wetted materials include stainless steel, PEEK, PPS, and EPDM to ensure chemical resistance and fluid compatibility.
