RSF VALVE is a leading manufacturer of oil and gas industry valves. We have more than 15 years experience in producing gate valve, globe valve, swing check valve, ball valve, Butterfly Valve, bellow seal globe valve, bellow seal gate valve, etc.
Application of below seal gate valve and below seal globe valve:
Hot oil system, steam system, hot and cold water system etc. Bellows seal valves help eliminate fugitive emissions of toxic or regulated fluids and prevent corrosive or harmful atmospheric conditions from entering the process. They also minimize maintenance and reduce life cycle costs in process plants including steam, cryogenic, heat transfer oil and vacuum systems. Fugitive Emissions - Complies to ISO 15848-1: 2006 Class AH leakag. SIL3 Safety Integrity Level for Automated Valves. The bellows lifecycle is designed as per MSS SP-117
Features:
- Metal bellows seal the moving stem and increase durability of packed stem seal valves
- Bellow provide a barrier between the stem at its point of entry through the pressure boundary and the process fluid within the valve, to eliminate stem leakage
- An anti-rotation device is provided in the bonnet to ensure bellow does not get twisted during assembly and disassembly or by vibration
- Bellow-sealed valves are usually leak tested using a mass spectrometer to detect leakage rates below 1x10E-06 std.cc/sec.
- Bellow-sealed bonnets are backed up with a standard stem packing set and a leakage monitoring port between the bellows and the packing in order to prevent catastrophic release of hazardous fluid in the event of a bellows leak
-
Bellow seal element. The key part of bellow sealed globe valves is mental bellow. It is the connection between cover and stem with automatic roll welding. The mental bellow can keep the stem part no leakage.
-
.Ergonomic hand wheel. It provide longer service life and easier operation.
-
Grease nipple. It can direct lubricate the stem, nut and sleeve.
-
Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal.
-
Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life.
