single & double acting Hydraulic Rotary Actuator , red electric
hydraulic actuator
VESON HSF series hydraulic actuators single & double
acting actuators are similar to VSF scotch yoke pneumatic
actuator range.
Many components are interchangeable, the only major difference is
the hydraulic power cylinder..
- Fabricated entirely from carbon steel.
- Low pressure carbon steel hydraulic cylinder suitable for supply
pressures up to 100 bar design.
- High pressure carbon steel hydraulic cylinder suitable for supply
pressures up to 200 bar design.
- Carbon steel piston with dynamic floating O-ring seals coupled with
lubricating piston guide rings.
- Carbon steel spring cartridge (only for single acting) with safety
facility which allows safe installation and removal of the whole
cartridge assembly.
- Visual position indicator directly connected to the valve stem
showing actuator / valve full linear stroke.
- 17.4 PH stainless steel piston rod, which prevents corrosion and
allows for minimum sliding friction on dynamic seals.
- ASTM A 320 L7 alloy steel tie rods, with standard electrolytic zinc
coating according to ASTM B633 FeZn 12 (thickness 12 μm).
- Carbon steel mounting adapter with bottom flange machined according
to the valve top mounting with carbon steel nickel-plated special
coupling mechanism. Optional for wedge gate valves: coupling with
hammer blow effect to facilitate valve unseating.
- Alloy steel galvanized end stoppers available on request.
- Integral manual override facilities.
TECHNICAL SPECIFICATIONS
- Supply pressure up to 200 bar design.
