PN25-DN150 triple eccentric structure Hastelloy alloy C276 material butterfly valve

【1】 Structure Introduction

This butterfly valve adopts a triple eccentric structure, and the butterfly plate sealing ring is a triple eccentric multi-level hard sealing structure. The material is a sandwich layer of metal steel sheet and graphite, that is, one layer of metal steel sheet, one layer of graphite, and another layer of metal steel sheet. The specific number of layers varies depending on the specifications, pressure, and manufacturer. Common SS304+graphite, SS316+graphite, etc. can also be used to produce soft sealed butterfly valves with three eccentric structures, such as PTFE, RPTFE, EPDM, NBR, Viton, etc.

Characteristics of Three Eccentric Butterfly Valve:

1. Short structural dimensions, small volume, light weight, and operational aspects

2. Adopting a full axis mechanism, the butterfly plate has high strength and a large overcurrent area

3. The unique three eccentric design reduces sealing friction loss and greatly extends the service life

4. Metal hard seal is resistant to high temperature, low temperature, high pressure, and has a wide range of applications

【2】 Related standards for national standard butterfly valves

Design and Manufacturing: JB/T8527

Structural length: GB/T1221

Connecting flange: GB/T9113

HG/T20592

Inspection and pressure testing: GB/T13927

GB/T9113 is the flange connection size of the national standard, and HG/T20592 is the flange size of the Ministry of Chemical Industry standard. We have summarized them into the national standard, and the flange connection size of the two is basically the same. Therefore, our company can process and produce according to customer requirements.

All valves produced by our company are strictly pressurized according to the pressure testing standards. Only after passing the pressure testing can zero leakage butterfly valves be allowed to leave the factory.

According to the GB/T13927 standard, strict pressure testing can achieve zero leakage under the above pressure strength.

Accept sampling and full inspection from the customer's quality inspection and third-party quality inspection units commissioned by the end customer, but please inform us in advance
