Cast iron pipe clamp valve-Other valves-上海冠环阀门制造有限公司

Product Overview

Cast iron pipe clamp valve, also known as cast iron pipe clamp valve or cast iron rubber pipe valve, consists of left and right cast iron valve bodies, rubber pipe sleeves, large and small valve stems, upper and lower gate plates, pull rods, brackets, handwheels, and other parts. Wear resistance, anti-corrosion, frost resistance, and good sealing performance. Simply replace the rubber sleeve and it will be as good as new. The valve body can be permanently used, with a lifespan of 4-6 times that of ordinary valves. There are various driving methods such as manual, pneumatic, and electric, and non-standard products can also be customized according to customer needs.

Operational Principle

When turning the handwheel clockwise, the large and small valve stems simultaneously drive the upper and lower pressure plates to compress the pipe sleeve for closure. Reverse to open, so that the pressure plate moves up and down between the pull rods to complete the valve opening and closing work.
