Single-Acting-Spring-Return Hydraulic Actuator Pneumatic Scotch Yoke Actuators c/w Hydraulic Manual Over-ride
Design and Construction
VSF series actuators provide global customers with the latest in valve actuation design, it is a highly unique and reliable means of operating ball, butterfly or plug valves along with 90 degree rotating mechanisms.
Modular Design
VSF series actuators share a modular construction design. The center body is available in six sizes. A pneumatic or hydraulic cylinder can be attached to either or both sides. A spring cartridge can also be fitted to either side for ESD (emergency shut-down) applications. Modular construction and stocking of components by VAA facilitates quick delivery times.
Robust Yet Lightweight Design
Totally enclosed weatherproof center body fabricated in carbon steel or ductile iron provides an excellent strength to weight ratio. The mechanism of piston and yoke has an advantage torque output.
Manual Override Options
A dependable manual override facility is an important part many valve/actuator applications. A variety of override options available to meet virtually any requirement. Available options include open or enclosed screws in both gear reducer and. declutch override gearbox, as well as a number of hydraulic override solutions.
VSF actuators are available with either B or C body modules. The B body modules provide efficient operation at both the break and end positions. The C body modules have a torque advantage in applications where higher break torque is needed to unseat the valve, with less critical needs at the run or fully open positions.
The Mounting Flange is up to the ISO 5211.
Operating Ranges SY actuators have torque outputs for spring-return models in excess of
110,000 Nm and double-acting models in excess of 240,000 Nm.
Operating pressures are: 3~10Bar
Operating temperatures standard -20°C to +80°C.
Optional trims include High Temperature -15°C to +150°C; Low Temperature -40°C to +80°C.
Integral bi-directional travel stops, adjustable from -6°to 96°of total valve travel, assist the HP Series in prolonging valve seat integrity.
Made from the low friction, long-life compound material, to avoid the direct contact between metals. The maintenance and replacement are easy and convenient.
