รายละเอียดสินค้า
The SCV is a robust cast valve with butt-welded ends.
Welding neck flanges can be welded on.
The valve disc made of chrome steel reduces abrasions.
The valve discs of installed valves can be replaced via the inspection and assembly opening.
The seal seat is manufactured by deposit welding and can be hard-coated if necessary.
Extremely reliable check valves are needed to protect steam and gas turbines from reverse flows. With their reliable, non-jamming closures, our SCV valves are optimally designed to fulfill this important protective function.
SCV check valves efficiently protect steam and gas turbines from back-flows coming from steam extraction pipes. This is guaranteed by a free-swinging model that closes automatically by means of its own weight. This enables it to swing closed against a double bearing friction moment without the assistance of a drive system. This makes extremely short closure times of under 0.5 seconds possible.
A hydraulic or pneumatic drive can be added as a closure aid by means of a two-part stem construction.
