Product Description

 Th

Pneumatic manual pressure regulating valve(JYQ21-25)

1 Overview
The function of the manual pressure reducing and overflow valve in the ground blowout preventer control device is to reduce the high pressure oil (21Mpa) in the accumulator to the lower pressure required to control the blowout preventer (usually 10.5Mpa). In addition, under certain working conditions, the valve also has the function of automatic overflow and pressure reduction, so the method has two functions: oil tines and overflow.
