A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions.
Can you use butterfly valves on steam?
Butterfly valves are utilized in a variety of applications. They are ideal for slurry and large volume water applications. These are also used in other applications such as vacuum services, compressed air or gas applications, and high-temperature and high-pressure water and steam services.
Can I use a globe valve for steam?
Globe valves are used mainly for steam or other media where a throttling service is required. The seat design gives an advantage for doing this by utilising its globe shape as it comes down to connect with the seat effectively cutting the flow gradually up until it seals completely on the seat face.
Which type of valves is best used with steam?
By far the most widely used valve type for the automatic control of steam processes and applications is the globe valve. It is relatively easy to actuate, it is versatile, and has inherent characteristics well suited to the automatic control needs of steam.
Can I use a gate valve for steam?
They are suitable for most fluids including steam, water, oil, air, and gas. Gate valves may have either a solid or flexible wedge disk. In addition to on/off service, gate valves can be used for regulating flow, usually in sizes 6 in.
Are Red valves for steam?
2-Way/2-Position, Normally Closed Steam and Hot Water Solenoid Valves. Performing safely and efficiently, these valves are designed for high-temperature fluid applications involving steam or hot water.
What type of valve is a gate valve?
A gate valve is the most common type of valve used in any process plant. It is a linear motion valve used to start or stop fluid flow. In service, these valves are either in a fully open or fully closed position. When the gate valve is fully open, the disk of a gate valve is completely removed from the flow.
What are the basic components of a gate valve?
Gate valves consists of three main parts.. body, bonnet, and trim. The body is generally connected to other equipment by means of flanged, screwed or welded connections. The bonnet, which containing the moving parts, is attached to the body, usually with bolts, to permit maintenance.

What is rising stem gate valve?
Rising stem gate valves have the threads external to the valve body. The gate valve stem is moving up when the valve is opening. Rising stem valves are usually made from cast or forged steel while non rising stem valves are more typically brass, bronze or cast iron.
Can you use a ball valve on steam?
Ball valves are commonly used in steam, water, oil, gas, air, corrosive fluids. They can handle slurries and dusty dry fluids. Ball valves are not used with abrasive and fibrous materials as it poses risk of damage to the seat and plug surface.
Can you use brass ball valves on steam?
Typical connections for steam valve are threaded, flanged, or compression fitted. Materials of construction can be aluminum, brass, bronze, cast iron, copper, steel, and stainless steel. Manual devices are opened or closed via a hand-operated wheel or crank.
