 The valve is intended for
opening/closing a line delivering liquid or gas. The control is realized by the pilot gas.
The high reliability and service life are ensured by:
- application of stainless steels;
- bellows control drive of welded design;
- full tightness of the pilot cavity excluding loss of the pilot gas;
- high tightness of the closing element.
The valve is designed for operation on cryogenic media.
It could be used also in "heated" lines with working media temperature of up to 400°C.
