1. Design
Lift check valve to DIN/EN with butt weld or socket weld ends, Y-pattern, check disc with closing spring, pressure seal design, Hastelloy-faced body seats.

2. Application
Industrial plants, power stations, process engineering and shipbuilding. For water and steam. Other non-aggressive fluids such as gas or oil on request.

Nominal sizes	DN 10 to DN 50
Nominal pressure	PN 250 to 500
Permissible operating temperature	-10 to +580°C
Permissible operating pressure	500 bar

1 Robust design made of forged steel.

Extremely robust material with a very dense, homogenous and fine-grained microstructure enables the valve to withstand high stresses.
Ideal for very high pressures and temperatures.

2 Economically efficient due to Y-pattern. Excellent zeta values and little pressure loss.
3 Added safety due to pressure seal design providing safe sealing to atmosphere:

The higher the pressure in the body, the tighter the bonnet joint. Very low risk of leakage, particularly at high pressures and temperatures. Compact design.

4 Long service life and high functional reliability:

Hard-faced valve seat made of wear-resistant and corrosion-proof Hastelloy.
Closing spring made of stainless steel as a standard for variable installation positions.
