Design features
1: Zero leakage seal.
Main seal: Bellows assembly seal, with built-in flush-free design,
by hydraulic forming, multi-layer structure, can ensure maximum life extension, expansion and contraction (open/close) up to 10,000 times

at a pressure of 2.5 MPa.
Auxiliary seal: non-metallic packing, using braided packing with corrosion 
inhibitor, for added reliability, safety and resistance to high temperatures,

providing a maintenance-free condition.
2: Internal limiting device,Increase the upper limit of the valve stem to
protect the safety of the valve in use, effectively protecting the elastic variables

of the bellows and greatly increasing the service life.
3: Sealing surface made of carbide overlay welding, excellent isolation.
4: The bellows is made of special material Hastelloy HC.276.
