Pilot Operated Safety Valve manufacturer in USA

Pilot Operated Safety Valve Manufacturer in USA are designed to be low noise and have high operating stability. They can be remotely controlled and unloaded using a drain port, which helps protect pumps and control valves.

Functions:
The pilot valve is fed system pressure through a pressure tapping line. The pilot valve then uses this pressure to control the closing force on the main valve disc. As the pressure increases, the closing force increases until the pilot valve opens. When the pilot valve opens, the main valve allows process media to discharge and relieve pressure at a set point.

Advantages:
Leakage control
Pilot Operated Safety Valve Manufacturer in USA has a bubble-tight construction and ability to be fully open at less than 10% above set pressure make them a good choice for product conservation and reduced fugitive emissions.
High operating pressure
Ability to handle higher operating pressures increases throughput and process output.
Precision control
High accuracy and responsiveness make them a good choice for fluid flow control.

Pilot Operated Safety Valve Manufacturer in USA below are the industries:
Oil and gas
Power generation
Chemical
Pulp and paper

Components:
Main valve
The main valve has an unbalanced piston assembly that’s exposed to more pressure on top than on the bottom. Pressure holds the main valve closed, not a spring.

Pilot valve
The pilot valve loads a diaphragm or piston to increase downward force, which opens the main valve. The pilot valve consists of a poppet, spring, and adjusting screw.

Solenoid valve
A direct-acting solenoid valve affects the pressure balance above and below the piston or diaphragm.

Resilient seat
A resilient seat is usually attached to the lower end of the valve.
