Product Description
Overview
Cast Steel Flanged Globe Valve
The closing element of J41H and J41Y cast steel flanged globe valves is a cylindrical valve disc, with the sealing surface being flat or conical. The valve disc moves linearly along the centerline of the fluid. National standard globe valves are only suitable for fully open and fully closed positions and are generally not used for flow regulation. However, customization allows for adjustment and throttling. With nominal pressures of 1.6 MPa to 16.0 MPa and working temperatures ranging from -29°C to 550°C, these valves are used in various industries such as petroleum, chemical, pharmaceuticals, fertilizers, and power generation to cut off or open pipeline media. They can be operated manually, with gear transmission, electrically, or pneumatically.
Structural Features:
1. Simple structure, relatively convenient for manufacturing and maintenance.
2. Short stroke, quick opening and closing time.
3. Good sealing performance, minimal friction between sealing surfaces, and longer lifespan.
Execution Standards:
1. Design specification: GB/T 1223.
2. Structural length: GB/T 12221.
3. Flange connection: JB/T 79.
3. Testing and inspection: JB/T 9002.
4. Product identification: GB/T 12220.
5. Supply specification: JB/T 7928.
