Design of the system and selection of proper components
Design of the system and selection of proper components play important part in operation, safety, performance, life, efficiency and maintenance of the system
In this issue, we are introducing a uniqueproduct‘ Relief-cum- Pressure Stabilization Valve’ fulfilling the requirements of Safety, Relief, Pressure controland also Pressure Stabilisation to be incorporated in the system, against the commonly used Relief Valves for achieving the following:
1. Accurate Pressure control 2. Best safety of system for Longer life 3. Effective Relieving for improving performance 4. Absorbing sudden pressure Surges, Jerks & Spikes
5. Offering Smooth pressure change and Stabilized pressure irrespective of setpressure for better system operation and improved Efficiency.
What is Relief-cum-Pressure Stabilization Valve
This is a unique Dynamically controlled Relief-cum-Pressure Stabilization Valve which not only perfectly Relieves and Controls the pressure but also Stabilizes and allows to change the operating pressure smoothly / uniformly, to the required pressure, absorbing all the shocks, irrespective of the pressure settings.
Working of Relief-cum-Pressure Stabilization Valve
The Dynamic Piston of the main valve remain closed at any operating pressure, less than the set pressure. For example, the Valve is set to be relieved at 175 bar and some operation is being carried at lower pressure of 50 bar, suddenly the pressure changes to 150 bar. As the dynamic piston is held closed through a low-pressure spring, the dynamic piston will not allow sudden Pressure Surge to effect the system, and move up, allowing the system flow at higher pressure to partly pass to tank and the operating pressure to gradually increase to the desired pressure of 150 bar.
The dynamic piston of Relief-cum-Pressure Stabilization valve instantaneously acts to dampen the pressure surge & let the pressure, in-spite of the fact the valve is set at a higher pressure of 175 bar, smoothly stabilizes at the required operating pressure being less than the set pressure.
