Key Features
Hydrovalves are manufactured by Alpeco in the UK and are constructed from high quality materials like gunmetal, brass and stainless steel, with nitrile seats, piston cups and gland seals. All components are readily accessible for easy servicing or for the fitting of replacement components.
The hydrovalve globe type body comes in ¾”, 1”, 1½”, 2” and 3” sizes all with BSP female threads. Hydrovalves come in 4 different versions:
o valves
- Designed for low pressure applications such as fluids up to 10psi
- Operated by a single air signal
- It is normally closed
HVG Single Acting Hydrovalves
- Designed to close when a signal pressure is applied to the top of the piston
- The pressure of flow the valve can control is proportional to this signal pressure
- Operated by a single air signal
- It is normally open
HVM Double Acting Hydrovalves
- Designed to be held in the closed position by a relatively light spring and the pressure in the top cylinder
- Opened by venting top cylinder and applying air pressure to lower cylinder
- Operated by two air signal
- It is normally closed
HVJ Pressure Balanced Hydrovalves
- Uses the pressure of the product to help close the valve and prevent valve hammer on closing.
- Operated by a single air signal
- It is normally closed
