Our Products
We offer the best product range of Piston Digital Control Valves and Hydraulically Operated Safety Valves.
Piston Digital Control Valve is an electrically actuated, hydraulically operated multi-function control valve. It can be used for local as well as remote controlled batching operations with electronic batch controller. The valve also offers an in-built flow governing function.
The Alma Piston Digital Control Valve works on the principle of balanced piston.
Piston is always exposed to high upstream pressure from its bottom side, whereas pressure in the piston chamber can be varied with the help of solenoid valves. When pressure in the piston chamber is equal to the high upstream pressure, the top spring acts as a differential force, pushing the piston down on the valve seat and the valve is held tightly-closed.
When pressure in the piston chamber is relieved with the help of solenoid valves, a differential pressure is created across the piston. The high upstream pressure below the piston overcomes the top pressure plus the spring force and pushes the piston up, resulting in valve opening and the flow starts.
Hydraulically Operated Safety Valve has been designed as a rapid action, internal safety valve to facilitate the emergency shut-down of tanks and vessels used for the storage and transportation of LPG, Ammonia, Vinyl Chloride and other hazardous liquids stored at high pressure and usually at ambient temperatures. The valve will FAIL-SAFE under all conditions.
The valve is normally held closed by a heavy duty stainless steel spring and hydraulic pressure is applied to hold the valve open. When the hydraulic pressure is released, the valve closes rapidly to ensure safe shut-down in the event of an emergency.
Hydraulic pressure can be released by :
