Single Stage Servo Valve

Single Stage Servo Valve

JASC’S Single-Stage Clevis Servo Valve is manufactured in a number of configurations. This Clevis Servo Valve is used to meter fluid or for position control. Its inherited pressure balance results in low electrical power consumption (1.0 watt max). The JASC Clevis Servo Valve is capable of 2-way or 3-way operation and offers a mechanical or electrical feedback. It offers other benefits such as low hysteresis and threshold.

JASC’s servo valves began production in 1991. JASC has since produced over 7,000 Clevis Servo Valves.  JASC rigorously tests every Clevis Servo Valve to ensure each one performs to the customer’s performance specifications. The execution of JASC’s testing program has resulted in over 60,000,000 hours of trouble-free service during field operations.

JASC Clevis Servo Valves can be refurbished, returning the valve to its original operating condition. This lowers the total cost of ownership significantly over servo valves that can’t be refurbished.

Development of the JASC Clevis Servo Valve has resulted in a series of design configurations, such as the Flapper Nozzle and FlexJet® Servos, which are used in applications such as animatronics and underwater marine environments.
