Andy Hatton
National Sales Manager – Gas
Flanged Parallel Slidevalve to EN12266 for gas. Temperature -20°C to +60°C. Double block and bleed.
The Series 777 Baurer valve is a double faced, parallel slide valve for natural and manufactured gasses. An advantage of the double door design is that, in the closed position, the valve is suitable for water sealing between the seats, thereby giving ultimate safety on the downstream side of the valve.
