Characteristics of electric globe valve
① The sealing surface of the valve disc and seat is made of hard welding, which is wear-resistant, high-temperature resistant, corrosion-resistant, scratch resistant, and has a long service life.
② The valve stem material is nitriding steel, and the surface of the valve stem after nitriding has high hardness, wear resistance, abrasion resistance, and corrosion resistance.
③ Due to temperature, pressure, and other factors, valve bodies and covers with diameters below DN50 are made of forged parts, while valve bodies and covers with diameters above DN65 are made of cast steel.
④ The valve body material variety is complete, and the packing and gasket can be reasonably selected according to actual working conditions or user requirements, which can be applicable to various pressure, temperature, and medium working conditions.
⑤ When installing the valve, pay attention to the flow direction of the medium and install it strictly in the direction indicated by the valve flow arrow.
⑥ Electric globe valves should be installed vertically as much as possible, with the valve stem facing upwards.

Structural characteristics of electric globe valve
1. Connection form of valve body and valve cover: PN10-64 adopts bolted valve cover; PN64-320 adopts a self sealing valve cover.
2. Valve stem nut: Generally, the valve stem nut material is ASTM A439 D2, and copper alloy or other materials can be used according to user requirements. For large-diameter globe valves, installing rolling bearings can effectively reduce the opening torque of the globe valve and make it easy to open and close.
3. Valve stem design: Made using integral forging technology, with the minimum diameter determined according to standard requirements.
Valve cover gasket form: PN10-64 globe valve adopts stainless steel graphite wrapped gasket; PN100 globe valve can use stainless steel graphite wrapped gasket or metal ring gasket; PN160 globe valves can use metal ring gaskets, while PN320 globe valves use self sealing metal rings.
4. Structural characteristics of globe valve: bolted valve cover, rising stem bracket, and metal cover of lifting valve stem.
5. Upper sealing seat design: All the globe valves provided by our company have reverse sealing design. Generally, the seat design of carbon steel globe valves adopts a separated reverse sealing structure, while the reverse sealing surface of stainless steel globe valves is very reliable. Although there is a reverse seal according to the standard API600, it is not a basis for replacing the packing under pressure.
6. Packing seal: Typically, molded flexible graphite is used as the packing material, and PTFE or composite packing materials can be provided according to user needs. The surface roughness of the contact between the packing and the packing box is 3.2um, which can ensure a tight and freely rotating joint between the valve stem and the packing contact surface. The precision machined valve stem sealing surface roughness of 0.8um can ensure reliable sealing of the valve stem.
7. Valve Seat: Carbon steel globe valve seats are usually made of forged steel material, and the sealing surface of the valve seat can be spray welded with hard alloy according to customer needs. For globe valves with NPS ≤ 10 ", a separate threaded screw in valve seat is used. If the user needs to weld the valve seat structure, it can also be provided; The NPS ≤ 12 "globe valve adopts a welded valve seat structure; The valve seat of stainless steel globe valve is generally made of integral or directly machined after welding hard alloy on the body. If the user has a need, the stainless steel globe valve seat can also adopt a separate threaded and welded seat structure.
