Metal seated DIN swing check valves
“RT gate valves valvole in cast design are used to prevent backflow in pipe systems. Due to their fully open design, this results in minimal pressure drop.
Design:
* The housing material is made of cast steel. The valves have a bolted or pressure seal bonnet (for higher pressure).
* The valve disc is made with forged material. On request, the disc can be supplied with an overlay of Stellite or other materials.
* The disc hinge joint is designed in such a way to achieve a
perfect tightness, which means a self-positioning disc system. “
Piston check and piston closing check valve, forged, metal seated
Wakmet piston check valves made of forged steel prevent the backflow of medium into the pipe. The check valve can also be used as a shut-off valve to open and stop the flow.
Depending on the model, the temperature ranges extend up to 530°C or 670°C (up to ≤ 200°C for PTFE).
Wakmet metal seated piston check valves are mainly used in the energy sector as well as in the pulp and paper industry. Depending on the type, they are suitable for media such as water, steam, non-aggressive and non-toxic media as well as some also for gas, fuel and sea water.
PTFE disc check valve
The DTEF from Chemvalve-Schmid is a high-quality PTFE check valve.
The check valve was developed especially for use in PTFE- lined pipe systems and for chemically aggressive media.
The metallic support ring encloses the PTFE parts and therefore protects the valve from deformation damage.
Xtreme disc check valve forged
The forged ChemValve-Schmid check valve DSL is designed for high pressure and high temperature environments due to its special housing design.
The wide range of different materials allows to use it for corrosive media and operating temperatures up to 500°C.
The check valve DSL can be used in all industrial processes with liquids, gases and steam.
