Overview

J941H electric globe valve is a valve that opens, closes, and regulates fluid channels by driving the valve disc vertically up and down along the centerline of the valve seat channel through the valve stem. The sealing pair (valve disc and valve seat) adopts a metal hard sealing structure, usually welded or embedded with hard alloy, which has the characteristics of high hardness, wear resistance, and high temperature resistance. The valve is connected by flanges and fixed to the pipeline flange with bolts. Valves rely on electric devices (usually multi turn electric actuators) to drive the valve stem, converting electrical energy into rotational torque and linear thrust, thereby accurately and reliably controlling the opening, closing, or positioning of the valve disc. This valve is particularly suitable for high-temperature and high-pressure working conditions that require remote automatic control, high-precision regulation, or lack of gas source.

feature

1. High sealing reliability: Adopting a metal hard sealing structure, the valve disc and seat sealing surface are welded with hard alloy and precision ground to achieve tight metal line sealing under high torque thrust of the electric actuator. The sealing level can reach ANSI Class VI or above, suitable for high temperature, high pressure and zero leakage harsh working conditions.

2. Precise control and flexible adjustment: The valve disc moves vertically in a straight line without obstruction, and with high-precision electric actuators and positioning feedback systems, it can achieve precise opening control and stable positioning, meeting the requirements of process automation adjustment.

3. High temperature and pressure resistance and erosion resistance: High temperature and pressure bearing valve body materials (such as WCB/WC6/CF8) and hard alloy sealing surfaces are used, which can withstand PN160 pressure and high temperature ≤ 550 ℃, and have good erosion resistance to steam, high-speed fluids, and particulate media.

4. High fluid resistance: The valve chamber channel is designed in an "S" shape with a non straight through design, and the flow direction of the medium needs to be reversed. When fully opened, the flow resistance coefficient and pressure loss are higher than those of gate valves and ball valves of the same specification, and the system design needs to consider additional pressure drop.

5. Compact structure but high installation space requirements: Compared with butterfly valves and ball valves, globe valves have a larger height and length structure, requiring sufficient installation and maintenance space to be reserved, especially considering the installation position of electric actuators and auxiliary electrical units.

6. High integration of intelligent driving: adopting multi turn electric actuators, supporting 4-20mA, bus communication and other control methods, with functions such as torque protection, fault diagnosis, and power-off self maintenance, suitable for non gas source or highly integrated automation systems, supporting remote centralized control and intelligent adjustment.
