Triple offset high-performance butterfly valve
Product overview:
The triple-offset butterfly valve, when closed, experiences uniform pressure and high pressure resistance, with zero friction between the valve seat and the valve plate. It is suitable for applications involving liquids, gases, steam, and high-viscosity media, as well as in environments with abrasiveness, corrosiveness, and high temperature and pressure.
Technical parameters:
Nominal diameter: DN50-DN1600/2"-64"
Pressure rating: PN6-PN64 / CL150-600
Operating temperature: -29℃ to 425℃ (or as per customer requirements)
Connection methods: flange type, clamp type
Drive methods: manual, electric, mechanical, hydraulic, etc.
Medium used: Natural gas, liquefied petroleum gas, coal gas, oil, water, steam
