This kind of flexible wedge gate valves are made from Gray iron(HT200) or Spheroidal graphite cast iron， which is idea on the pipelines for water, sewage, city water, steam, oil, gas,etc.

Features of Wedge Gate Valves:
 Flat seat design avoid blocking up by stone, sludge, wooden blocks etc.
 Flexible wedge makes high tightness.
 Painted by epoxy, have good corrosion protection.
 The design of stem reduce the resistance of open & close.
 Made from casting iron, is stronger& lighter than traditional ones, easier for maintance.
 Sizes: 2" - 40" or DN50 – DN1000
 Working pressure: PN 16 - PN 160
 Working temperature: 80 C degree
 Medium: normal temperature liquid
