Direct sales of butt welded globe valveThe design and manufacturing comply with API602 and ASME B16.34. Inspection and testing follow API 598, and marking follow MSS-SP-25. When maintaining, attention should also be paid to water ingress in the electric head and its transmission mechanism. Especially rainwater that seeps in during the rainy season. After the over torque protection action, manual operation is also unable to switch on and off. If forced, it will damage the internal alloy components. One is to rust the transmission mechanism or transmission shaft sleeve, and the other is to freeze in winter. Excessive torque during electric valve operation can damage transmission components, causing the motor to be unloaded or the over torque protection to trip and prevent electric operation. The transmission components are damaged and manual operation is not possible.

Selection principleYes: On pipelines with lax flow resistance requirements. Places where pressure loss is not given much consideration. Small valves can be selected from needle valves, instrument valves, sampling valves, pressure gauge valves, etc. Globe valves should be used on pipelines or devices for high-temperature and high-pressure media. Such as thermal power plants and nuclear power plantsHigh temperature and high-pressure pipelines in the petrochemical system.

Direct sales of butt welded globe valveadvantage

1. Good sealing performance, low friction between sealing surfaces, and long service life.

2. The structure is simple, and manufacturing and maintenance are relatively convenient.

3. Small work schedule and short opening and closing time.

Key Features:

1. The external thread of the valve stem ensures its high-temperature service life;

2. The handwheel is made of steel plate stamping, which is durable. The handwheel does not lift or lower when opening or closing, making it suitable for smaller spaces;

3. Temperature up to 450 ℃;

4. The throttle valve core brings good regulation performance;

5. In addition to packing, stainless steel corrugated pipes are also used as sealing components.

6. The imported butt welding globe valve has a double-layer corrugated pipe sealing device, with zero external leakage;

7. Imported welded cut-off valve stem, maintenance free, long service life; Ensure double safety through secondary packing sealing;

8. Equipped with position display and preset travel/anti rotation device.
