The BP series are upstream pressure control valves. These are general purpose self operated pressure relieving valves for controlling many kinds of fluids and gas. The opening of these valves is in proportional to the rise in inlet pressure beyond set value. Different soft sealing discs are available for different fluids and gas.

These discs can be handle wide range of pressure and temperature up to 150 C .ensure shut off the metal sealing surface are carefully lapped at higher temp. These back pressure regulating valves are very well suited for high and varying pressures.

Features:-

 

1. Gland less ConstructionThe glandless design scores over conventional solution such as below seals etc, where positive zero gland leakage is required as the gland its self is eliminated. Gland less construction results in improvement of sensitivity and repeatability of the valves, as it eliminated hysteresis.
2. Wide range of flow To satisfy the varied flow requirement, wide range of body sizes and parts diameters are available.
3. Accuracy of valvesLarge actuating areas provided more precise control even at low pressure settings.
4. Easy to maintainActuator internals valve disc are holder can be inspected and replaced without removing regulator from pipe line

When air pressure at the inlet port is reduced a differential in the pressure acting on the diaphragm is created. The differential in pressure lifts the diaphragm from the exhaust port and seats it on the inlet port. This opens the port allow air to flow freely from the out let port to atmosphere and close the inlet port.
Should outlet air pressure drop below inlet pressure the differential in pressure seats the diaphragm on exhaust port stopping further exhaust.
