135A – High Temperature DN50 Sampling Valve

The 135A sampling valve is equipped with a metallic piston (Stainless Steel, Hastelloy) for sampling process up to 300ºC (572ºF). Unlike the PTFE or PEEK piston, the metal piston has a high temperature gasket around it. To avoid any damage when closing the piston, the gasket is receding into the piston and seals against the valve cylinder wall making contact only after the final sealing turn of the handwheel. Tightness from vacuum up to 10 bar (145 psi).
