Low Tempreture Control Valve, specially designed for the circumstances that require a tight shut-down in low temperature, is ideally suitable for media of low temperature such as liquid oxygen and liquid nitrogen with multifunction and reliability with low cost.
Thinktank type pneumatic diaphragm single seat regulator is the the most commonly used actuator in automatic control system, it is composed by pneumatic diaphragm actuator and low flow resistance regulator. Single seat is applicable to occasions that is strict for leakage, low pressure differential around valve and has a certain viscosity and contain fiber medium, Two seat valve has small unbalanced force, large allowed pressure differential, large flow capacity and other characteristics. It is applicable to occasions that is not strict for leakage, sleeve valve has good stability, not easily vibration, low noise, small temperature sensitivity, is applicable to large pressure differential and not strict for leakage occasions.
