Manual Actuators HVA Series
For operating quarter turn ball valves and butterfly valves, Huima Specials has developed the HVA Series, a wide range of standard actuators.
The actuators can be equipped with a spur or bevel gear reduction to minimise the required input torque.
Thanks to in-house engineering and production Huima Specials is able to meet your special requirements.
The HVA Series have several outfits:
- S-series Standard
- M-series Marinised service
- W-series Water service
- B-series Buried service
- Shockproof (440G - TNO-tested).
Construction: Housings can be chosen from GG25 or GGG40 (nodular cast iron).
Torque: For manual operation.
Range: HVA gear systems make a 90° turn.
Self Braking: All gear systems are self-braking.
