The extended stem gate valve is a specialized type of valve usually designed for cryogenic applications and underground installations. This valve features a stem that is longer than standard gate valves, allowing for easier access and operation.
Generally, FLOWORK uses Jotun brand. We can also paint valves according to customer’s requirements.
We are delighted to invite you to the upcoming OFFSHORE TECHNOLOGY CONFERENCE, which will be held from 5th to 8th, May, 2025 at NRG PARK, HOUSTON, TX, USA. We would be honored to have you visit our booth 3402.
Generally, valves are equipped with extended stems in the following two situations.
PTFE is the most basic sealing material for ball valves with excellent corrosion resistance and low friction coefficient. It can provide good sealing performance over a wide temperature range.
There are several types of discs used in globe valves, each with its own design and characteristics. Some common types of discs used in globe valves include:
The low-temperature valve drip tray is a device designed for use in low-temperature environments to collect and discharge water droplets from valves.
If ball valve is soft sealed, static electricity will be generated on ball and seat during opening and closing process, which can easily generate sparks that are likely to cause the medium to burn or explode if the medium is flammable and explosive.
This structure is simple and is easy to be manufactured. However, the disc and seat are always in a state of compression and scratching, resulting in a large resistance distance and fast wear.
Flange connection is composed of flange, gasket, and bolts and nuts. It is a detachable connection that can be used for connecting pipes to valves, pipes to pipes, and pipes to equipment.
The strength performance of a valve refers to its ability to withstand medium pressure.
