Product Description

Rising Stem Globe Valves

Specifications:

The traditional rising stem globe valve can be used for isolation and throttling services. Although these valves exhibit a slightly higher pressure drop than straight-way valves (such as gates, plugs, ball valves, etc.), they can be used in situations where the pressure drop through the valve is not a controlling factor.

Size: DN15-DN1000

Pressure: PN10/PN16

Standard:  GB/T12237-1989,GB/T13927-1992

What is a rising stem globe valve?

The rising stem globe valve is a linear motion valve mainly designed to stop, start and regulate flow. The disc of the rising stem globe valve can be completely removed from the flow path, or the flow path can be completely closed. The rising stem globe valve regulates the flow in the pipeline and provides positive shut-off capabilities. The rising stem globe valve has a cast steel valve body, valve trim and flange connection. The valve is operated by a rising rod.

rising stem globe valve is a type of gate valve which is able to follow the opening/closing position by moving the stem up & down movement, is able to follow electronically the movement by adding a monitoring key, and full open position does not disrupt the flow. rising stem globe valve generates low head loss according to butterfly valves.

Since the entire system pressure exerted on the disc is transmitted to the valve stem, the actual size of these valves is limited to NPS 12 (DN 300). The rising stem globe valve larger than NPS 12 (DN 300) is an exception rather than a rule. Larger valves require tremendous force on the valve stem to open or close the valve under pressure. The rising stem globe valve up to NPS 48 (DN 1200) has been manufactured and used.

The rising stem globe valve is widely used to control flow. The flow control range, pressure drop and load must be considered when designing the valve to avoid premature failure and ensure satisfactory service. Valves that withstand high differential pressure throttling services require specially designed valve trims. When minimum restrictions are required, the gate valve design makes it ideal for the free flow of fluids. When the gate valve is fully opened, the gate is completely sucked into the valve body, so that the pressure and flow through the valve are consistent with the connected pipeline.
