API 304L Bellow Sealed Stop Valve
Product Description
Size: 2′′-12′′ Ends Con.: RF,Rtj,Sw,Bw Trademark: fyv Origin: Wenzhou, Zhejiang Class: 150~1500 O-Ring Sealing: PTFE,NBR,Rptfe Specification: CE, SGS HS Code: 8481804090 Product Description
Leakage from the valve gland is often a problem for environment protection & sometime it is quite dangerous if such leakage is from a hazardous fluid. Bellow seal valves are designed with a bellow cartridge welded to the valve bonnet and stem, so that when the stem up & down movement makes the bellows expands & compress. Therefore there is no sliding or rotating seals through which process fluid can leak.
Design Standard:
Products Range:
Type: Gate, Globe
Size: 2"~12"
Rating: ANSI 150lb ~ 1500lb
Body Materials: Carbon Steel, Stainless Steel, Alloy Steel, Duplex Steel
Bellow Materials: Stainless steels, Inconel
Design Feature:
Formed bellow
10, 000 cycles bellow without failure
Zero stem leakage
Minimum maintenance cost
