The CST-K from ChemValve-Schmid is a PTFE lined butterfly valve with a plastic housing. The housing made of Duraplast thermosetting plastic reduces the weight of the valve and therefore provides savings on the pipe construction. Plastic is also more resistant to corrosion than standard housing materials such as cast iron and cast steel.
The PTFE lined butterfly valve with a Duroplast housing is produced to the highest quality standards for the safe handling of aggressive media. Spherical structural elements reduce friction and therefore increase the service life. The PTFE lined butterfly valve is designed for use with highly chemical media and is therefore used in almost all industries.
The throttle valves RD and RA are designed as a wafer type valve with a centric valve disc and are suitable for operating temperatures up to 800°C, depending on the choice of material.
For flanges according to DIN EN 1092-1 or ASME B16.5 / ASME B16.47. Lengths according to the company standard.
Connecting flange for actuators to DIN EN ISO 5211.
Testing according to DIN EN 12266.
Versions:
RD without seat (leakage approx. 1% of surface equivalent),
RA with metal travel stop ring (leakage approx. 0.5% of surface equivalent),
RA with seal ring (leakage approx. 0.3% of surface equivalent),
RA with metal travel stop ring with seal ring (leakage approx. 0.1% of surface equivalent)
“The Emreson resilient seated butterfly valve is a centric butterfly valve with a split shaft (up to DN300), rounded polished disc edge, centring bores on the valve housing and an extended valve neck allows for pipe insulation.
The type GRW is designed as a wafer type valve and the GRL as a flanged type valve according to EN558 series 20, with a spheroidal cast iron housing and a disc in 1.4408 steel. “
