Class150-900 cast steel globe vlave

Class150-900 cast steel globe vlave

Chardacteristics of API Gate Valve
1. Design and manufacture of product according to advanced standard such as ANSI B16.34, BS 1873 etc.
2. Configuration of body as elegant bucket or streamline, through-way port with small liquid resistance.
3. Blow-down part (disc) and face of seat utilize awl seal, with small strength to blow down, scour resistance and seal reliable.
4. Exchangeble seat, random combine the material of surface of blow down part to meet the requirement of work status, prolong
service life.
5. Big size, high pressure globe valve accordance with need of blow up and down strength, driving style of stem use lift style, fix rolling
bearing or use knock style hand wheel to reduce blow-down or blow-up strength.
6. Material of main body, material of trims, packing, washer, material of fastener can logically combine according to customers
requirement or actual work status.
