D660 Series Servo-Proportional Control Valves with ...
www.moog.comTwo-stage proportional valves are mainly used when low threshold and good dynamic response with small signals are required. The three-stage proportional valves are suitable for good dynamic response with large signals. By combining a fast first stage, a suitable spool drive area and integrated electronics, an optimum proportional valve can be ...
Direct Drive Analog Control Servo Valves D633 and D634
www.moog.comcompared with proportional solenoids with one force direction only. The closed loop spool position control and pulse width modulated (PWM) drive electronics are inte-grated into the valve. The integrated electronics of the valves features SMD technology with pulse width modulated (PWM) current output stage, and requires a 24 V DC power supply.
PVG 32 Proportional Valves Technical Information
www.imdl.gatech.eduThe LS pressure limiting valves save energy compared with the shock valves PVLP: • With PVLP all the oil flow to the working function will be led across the combined shock and suction valves to tank if the pressure exceeds the fixed setting. • With LS pressure limiting valves an oil flow of about 2 l/min [0.5 US gal/min] will be led
Electro-hydraulic Valves - A Technical Look
www.moogvalves.comThese valves do not need onboard electronics to operate. Electrical feedback (EFB) valves use an elec-tronic position transducer to measure the spool position. This signal is fed back electrically, and thus all EFB valves need control electronics to operate. Moog Valves usually have this electronics integrated into the valve design and require no
Oil 4/2 and 4/3 proportional directional - Robert Bosch GmbH
dc-kr.resource.bosch.comThe 2 spool position valves are, however, only equipped with solenoid "a" (7). Instead of the 2nd proportional solenoid, there is a plug screw (10). The 4/2 and 4/3 proportional directional valves are designed as direct operated devices in plate design. Operation is ef-fected by proportional solenoids with central thread and de-tachable coil.
