WJ41H bellows globe valve in detail:
Valve as the valve stem seals bellows. It is commonly used on the valve stem seal demanding applications, such as the occasion for high vacuumand nuclear industry. Instead of using bellows valves on ordinary stuffing orstuffing and use, can not leak stem position, in order to prevent radioactive substances or valuable substance leakage, or to maintain a high vacuum.The corrugated pipe with the valve stem down the stretch, the compressive strength and the fatigue strength of the maximum working pressure depends on the corrugated pipe.

Corrugated flange cut-off valve product overview: bellows seal globe valve,metal corrugated pipe seal using advanced manufacturing technology, high performance metal bellows, bellows seal globe valve with bellows seal design, the complete elimination of the common valve stem packing sealaging fast and easy leakage faults, not only to improve the use of energy efficiency, increase the safety of production equipment, reduce repair costs and frequent repair and maintenance, also provides a clean and safeworking environment.
Bellows globe valve widely used: petroleum chemical industry, chemical fiber textile, paper, plastic, rubber, printing and dyeing power steel food industry.
Bellows globe valve structural characteristics
1, product rational structure, reliable sealing, double rugged bellows seal design (bellows + packing), ensures zero leakage of the valve stem. No fluidloss, improve plant safety equipment. And sealed in line with international standards.
2, the sealing surface surfacing Co base hard alloy, wear resistance,corrosion resistance, anti friction performance, long service life
3, stem the tempering and surface nitriding treatment, with good corrosionresistance and friction performance; a valve rod lifting position indication,more intuitive
The 1 bellows seal gate valve, which is the key component of metalcorrugated pipe, and the lower end of the stem assembly with automatic roll welding, welding automatic roll and the upper end of the connecting plate,forming a metal barrier between the fluid medium and air, to ensure that the valve stem zero leakage;
2 valve used cone design, sealing surface and the dielectric into a streamlined, better sealing performance, longer service life;
3 double seal design (bellows + fill) if the bellows failure, valve stem packingwill prevent leaks, and sealed in line with international standards;
4 valve cover is provided with fatliquoring joints, can be directly to lubricate the stem, nut and sleeve, unlike traditional only for thread lubricating oil;
5 ergonomic design handwheel, longer service life, easy and convenientoperation, higher safety and reliability;
Bellows globe valve application:
Steam, thermal oil, toxic, strong corrosion liquid medium
Bellows globe valve for temperature:
-196 ~600 OC
