What Are The Types Of Hand Valve?
- Ball Valve: Features a spherical disc to control flow with a simple quarter-turn of the lever or handle.
- Gate Valve: Uses a gate or wedge-shaped disc to control flow, typically with a wheel-operated handle.
- Globe Valve: Provides precise flow control using a movable plug or disc and a stationary ring seat.
- Butterfly Valve: Utilizes a rotating disc to regulate flow, often with a lever or gear-operated handle.
- Needle Valve: Offers fine flow control with a threaded stem and needle-like plunger.
- Check Valve: Allows flow in one direction only, preventing backflow, and may be operated manually.
- Diaphragm Valve: Controls flow with a flexible diaphragm, suitable for handling corrosive or abrasive fluids.
What Is Hand Valve？
A hand valve is a type of valve designed to regulate the flow of fluids manually using a lever, wheel, or other hand-operated mechanism. It allows users to control the flow rate, direction, or shut off the flow completely by adjusting the position of the handle or lever. Hand valves are commonly used in various industries and applications where precise control over fluid flow is required, such as plumbing systems, hydraulic systems, pneumatic systems, and gas pipelines. They offer convenience, flexibility, and ease of operation, making them essential components in many fluid control systems.
How Does Hand Valve work?
Hand valves operate by manually adjusting a lever, wheel, or handle to control the flow of fluids. When the handle is turned or lever is moved, it either opens or closes the valve mechanism, regulating the flow rate or completely stopping the flow. Inside the valve, there’s typically a disc, plug, or other mechanism that moves to allow or block the passage of fluid. This manual operation allows users to precisely adjust the flow according to their needs, making hand valves versatile and essential components in fluid control systems.
