คำอธิบาย

Product Overview

วาล์วกลอบแบบหน้าแปลน J41H ASME is designed for shut-off and flow control service in ASME pipeline systems. WDL Valve supplies this valve in Class 150, Class 300 and Class 600 pressure ratings, with flanged ends, bolted bonnet construction and reliable sealing performance for a wide range of industrial applications.

The valve body and bonnet are designed with good strength, rigidity and flow capacity. The bonnet is equipped with a backseat structure, which helps improve packing sealing reliability when the valve is fully open and makes packing maintenance more convenient. Packing and gasket materials can be selected according to actual working conditions or customer requirements.

By selecting suitable body, trim, packing and gasket materials, the J41H globe valve can be used for water, steam, oil, nitric acid, acetic acid, strong oxidizing media, urea and other industrial media. Operation options include handwheel, bevel gear and electric actuator.

Working Principle

The opening and closing part of the J41H globe valve is a plug-type disc. The sealing surface can be flat or conical, and the disc moves linearly along the centerline of the flow passage. This structure provides reliable shut-off performance and better throttling control than many straight-through isolation valves.

Key Product Features

  • Compact and reasonable structure with stable sealing performance.
  • Suitable for shut-off and flow regulation service.
  • Backseat design improves packing sealing reliability in the fully open position.
  • Medium and large size valves can be equipped with rolling bearings for easier operation.
  • Multiple flange sealing face options are available to meet different project requirements.
  • Body, trim, packing and gasket materials can be selected according to pressure, temperature and medium.
  • Available with handwheel, bevel gear or electric actuator operation.
