WZ41H Bellows Gate Valve Product Overview:
The bellows gate valve adopts a bellows sealed design. Completely eliminating the disadvantages of aging and easy leakage of ordinary valve stem packing seals, not only improving energy efficiency and increasing production equipment safety, but also reducing maintenance costs and frequent maintenance. It also provides a clean and safe working environment. Applicable to nominal pressurePN1.6～4.0MPa,operation temperature-29～350℃Cut off or connect pipeline media on pipelines in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries.
working principle:
WZ41HThe bellows gate valve adopts a bellows structure inside, and the lower end of the stainless steel bellows is welded to the valve stem to prevent the process fluid from corroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. Adopting a dual sealing design, if the bellows fails, the valve stem packing will also prevent leakage. The bellows is welded to the valve stem to maintain stable operating performance and avoid valve stem vibration caused by valve plug vibration. The most suitable for pipelines containing steam, flammable, explosive, thermal oil, high-purity, toxic and other media.
Product features:
1Double sealing design (corrugated pipe)+If the bellows fails, the valve stem packing will also be avoided.
2Eliminate leakage and comply with international sealing standards.
3No fluid loss reduces energy loss and improves factory equipment safety.
4Long service life reduces maintenance frequency and lowers operating costs.
5The sturdy and durable bellows sealing design ensures zero leakage of the valve stem, providing maintenance free conditions.
