China Globe Valve Manufacturer and Supplier

Globe Valve

Short Description:

A Globe valve is a linear motion valve and is primarily designed to stop, start and regulate flow. The disk of a globe valve can be totally removed from the flow path or it can completely close the flow path.

Globe valves are extensively used to control flow. The range of flow control, pressure drop, and duty must be considered in the design of the valve to avert premature failure and to assure satisfactory service.

Conventional Globe valves maybe used for isolation and throttling service. Although these valves exhibit slightly higher pressure drops than straight-through valves(e.g., gate, plug, ball, etc.), they maybe used in applications where the pressure drop through the valve is not a controlling factor.

Valves subjected to high-differential pressure-throttling service require specially designed valve trim.

Product Introduction

As an extremely important cut-off valve, the globe valve plays an important role in cutting off and throttling the fluid in the pipeline. Its seal is to apply torque to the valve stem, and the valve stem applies pressure to the valve flap in the axial direction, so that the sealing surface of the valve flap and the sealing surface of the valve seat are closely attached, and the leakage of the fluid along the gap between the sealing surfaces is prevented.
