Product features of BUJ41S insulated plunger globe valve :

1. The structure of this lift-rod piston valve is simple, scientific, safe and reliable. It is particularly easy and flexible to open and close. Compared with the plunger valve, it has the advantages of light and fast opening and closing.
2. Unique sealing performance and no leakage. The piston has a dual-effect function composed of a metal and non-metal multilayer sealing structure.
3. One-piece valve seat (cylinder liner) radial conical sealing surface, high height, large contact area and good performance.
4. The selection of materials for piston rings according to different applicable media can comprehensively increase its range of use, high temperature resistance, wear resistance, corrosion resistance, strong resilience, etc. After a long period of use, the piston rings can be adjusted for pressure if they are worn and maintained. Increase the original state.
5. The technology of repairing and replacing the piston ring is simple and convenient. The valve body does not need to be detached from the pipeline. The valve cover assembly can be replaced after a steam outage, and the new piston ring can be replaced and used repeatedly.

Performance and principle of BUJ41S insulated plunger globe valve :

1.Insulation plunger stop valve consists of valve body, valve cover, gland, stem, valve plug, valve cover, piston ring, integrated cylinder liner (valve seat) lift rod nut, flat bearing, hand wheel, bevel gear, etc. The components are composed, and the wheel rotates and lifts the rod to drive the piston to reciprocate up and down between the inside and outside of the conical cylinder liner to complete its closing and opening.
2. The cylinder cone structure is tapered in the cylinder (valve seat) cone circular shape according to the applicable medium. Stainless steel or hard alloy is deposited and welded to a hardness of HRC40.
3. The sealing structure of the valve plug and piston ring has a multi-layer seal made of metal and non-metal. When a piston ring is worn out for a long time, the pressure has been adjusted to zero, and the pressure regulation has failed, so the second The metal cut-off conical piston plays the role of simultaneous sealing. Therefore, the service life of the piston valve is several times that of ordinary valves, so no special maintenance is required during use to keep it from leaking. The selection of a better opening and closing device without leaking pipes has obvious applications for saving energy, reducing labor and environmental pollution.
