Helium mass spectrometry leak detection: API 602 MSS SP-117

Application: Suitable for precise control of gas, liquid and other media process parameters such as pressure,flow, temperature, level at a given value. Particularly suitable for leakageswhere a high level of leakage is required.

Design features:

1: fluid channel is S streamline, small pressure drop loss, allowable differential pressure, low noise, in line with environmental requirements.

2: Pneumatic single seat valve adjustable range, inherent adjustable ratio of 50.

3: Piston type film shape actuator is more suitable for high frequency work,life test is 100000 times.

4: Exclusive bellows seal to improve service life and ensure good flow characteristics.

Actuators: electric, diaphragm type pneumatic, piston type pneumatic

Options: limit switches, filters, solenoid valves, emergency handwheels
