 The valve is intended for opening/closing
a line delivering liquid or gas, with simultaneous redirection of the working medium flow to another line.
The valve is controlled by
pilot gas.
The high grade of reliability is ensured by:
- application of stainless steels;
- welded design of the steel membrane drive;
- high leak-proofness of closing elements;
- high external leak-proofness;
- full leak-proofness of the pilot cavity excluding loss of the pilot gas.
