TVCCL globe valve works by controlling the flow of fluid through a pipe via a movable disk (or plug) and a stationary ring seat, which are housed in a typically spherical body.

Features

• Globe valves are particularly common in on-off services, but can be used for various applications
• Have a good shutdown function.
• Used for regulating flow in a pipeline.
• Nice shut off effect.
• Suit for frequent operation as no worries of wear of seat and discs.
• Easy to repair, as seat and discs can be accesses from the top of valve.
• Fast operation due to shorter stroke length.
• Often operated by automatic actuator.

Structure of the Valve:
The major components of a globe valve include the valve body, bonnet, stem, disc (or plug), and seat.
The body has a spherical shape, and the internal space is divided by a baffle. The disk and seat are on opposite sides of this baffle.

Operation Mechanism:
The globe valve stem, attached to the disk, extends outside the valve and connects to a manual or automatic actuator, such as a handwheel or motor.

Globe valves are widely used in the plant piping industry and can be operated manually or automatically. Unlike gate valves, globe valves will help regulate pressure flows and complete the flow of liquids or their complete shutoff.
Turning the actuator moves the stem, which moves the disk toward or away from the seat.

Flow Regulation:
Opening the Valve: Turning the actuator lifts the disk away from the seat. This creates a gap for the fluid to flow through. The more the valve is opened, the larger the gap, and the more fluid can flow through.

Closing the Valve: Turning the actuator lowers the disk towards the seat. As the disk approaches the seat, the gap for fluid flow decreases, reducing the flow rate. When the disk sits flush against the seat, the flow is completely stopped.

Throttling Capability:
Globe valves are particularly good at throttling flow. By partially opening or closing the valve, the operator can precisely control the flow rate. This is due to the shape of the disk and seat, which allows for a gradual increase or decrease in flow as the valve is operated.

Flow Direction:
In most globe valves, fluid enters the valve from below the seat. When the valve is opened, the fluid pushes against the bottom of the disk, helping to create a better seal when the valve is closed.

Applications

• Globe valve used for closed, switch often and used as throttling valves to control flow through.
• Globe valve is used in applications where flow needs to be regulated or where variable pressure is required in the pipeline. Such like treat water system, Fuel oil system and Turbine seals and drains.
• Widely used in petroleum refining, chemical, paper, pharmaceutical, water conservancy, municipal, steel and other industries
• Common used in general household water and gas pipelines.
• Applied to construction related equipment
• Suitable for pipelines of natural gas and power systems.

More Knowledge about TVCCL valve:

A globe valve is comprised of two halves, separated by an opening with a moveable plug or disc that can be screwed in, or unscrewed to open and close. They're most commonly used to open, close, or throttle flow in a system.
All globe valves are designed with a stem that moves up and down to regulate flow inside the valve, contains a disc (ball, composition, or plug), and seat which is generally screwed into the valve body. Seats are designed in plane parallel or inclined to the line of the flow.
