offer bimetal type

Features:
1) For strong applicability of condensate water volume, it can discharge intermittently
  or continuously
2) Large displacement double seat differential pressure mechanism and SCCV closing
  system are built-in so as to obtain small volume and large displacement
3) Convenient maintenance and services for whole internal components made of
  stainless steel and installed on bonnet
4) High backing pressure rate: 90%
5) Reliable gas-water separation (the vapor enters from the bottom of valve
  through shaped passage). The valve is always in water sealing state and
  effectively keeps the steam from leakage
6) The open-top float is water hammer resistant. The bucket is designed with
  overflow exhaust holes to effectively prevent the steam lock or air block
7) In combination with lever mechanism to compose high pressure valve
