Product Description

General


FREE-VALVE  Manual Control Rubber Lined Type Wcb Steel Weir Diaphragm Valve is a special form of on-off valve, disc is a diaphragm made of corrosion-resistant soft material,the diaphragm separates the bottom body cavity from the top bonnet cavity, so that the stem, metal disc and other parts above the diaphragm are not subject to media corrosion,so fluorine lined diaphragm valve eliminate the packing seal structure, and will not produce media leakage.

Features

 
  1. The diaphragm of using FEP/FPA/PTFE and rubber composite, suitable for variety of corrosive media.
  2. 100% gas seal can be achieved to ensure no leakage in outlet port.
  3. No direct contact between metal parts and medium slurry.
  4. Bi-directional and full flowing path can reduce pressure drop, weaken abrasion and prolong the service working life.
