Tianjin, China - September 20, 2026
WCB wafer butterfly valves are extensively used for cut off and throttling in industrial pipeline systems. Manufactured from ASTM A216 WCB cast carbon steel, this valve category is divided into two mainstream versions: soft seal WCB wafer butterfly valve and hard seal WCB wafer butterfly valve. Many procurement engineers get confused when choosing between them. Clear comparison of performance, working conditions and limitations helps avoid wrong model selection and unexpected field failures.
The soft seal WCB wafer butterfly valve [ https://www.tjkrvalve.com/stainless-steel-body-ptfe-seat-wafer-butterfly-valve-product/ ] adopts elastic rubber or PTFE as sealing components, such as EPDM, NBR. It achieves bubbletight zeroleakage sealing performance under lowtomedium pressure. Its advantages include low operating torque, good sealing effect and competitive cost. However, the temperature resistance is restricted by the elastomer. Normally it works within20 ~120. Hightemperature ...
