Mechanical valves are essential components in controlling the flow of fluids or gases in various industrial sectors such as oil and gas, chemical processing, power generation, and food production. These valves regulate pressure, temperature, and flow rate by mechanically opening or closing pathways.
A mechanically operated valve is a type of fluid-control device that uses mechanical force—either manual or externally applied—to move the valve core, enabling the opening, closing, or directional switching of air, gas, water, or other fluids.
These valves are essential components in pneumatic systems, hydraulic systems, industrial pipelines, and automated machinery.
Mechanical valves operated through levers, rollers, cams, plungers, gears, or linkage mechanisms, making them highly reliable in applications where physical actuation is required.
◆ Simple Structure & High Reliability
Fokca's mechanical valves have a simple structure, typically consisting of a valve body, valve stem, valve disc, and valve seat. They offer advantages such as long service life, easy maintenance, and stable and reliable fluid control, and can support automated operation.
◆ High-Pressure & High Temperature Resistance
This mechanically operated valve is designed for harsh environments and has the enduring resilience to high operating pressures, extreme temperatures, and continuous industrial use, making it ideal for oil and gas, power plants, heavy industry, and other demanding applications.
◆ Multiple Actuation Methods
Another key advantage of this type of mechanical valve is that, although the valve core is mechanically driven, it can be integrated into manual systems or fully automated industrial processes. It can be driven by automated tools including manual handwheels or levers, pneumatic actuators, electric motors, and hydraulic cylinders.
◆ Excellent Sealing and Corrosion Resistance
Finally, a noteworthy advantage is that modern mechanical valves utilize advanced sealing technology and materials, such as PTFE and rubber sealing rings, to achieve metal-to-metal seals.
Mechanically driven valves come in various styles depending on application,operating conditions,and system requirements.
The ball valve uses a perforated ball as the rotating element.
Characteristics:
Quick opening and closing with a pneumatic actuator; excellent sealing performance; this valve is ideal for fluid shut-off and emergency isolation.
Gate valves use a vertical gate that lifts or lowers to control fluid flow.
Characteristics:
Full open or full close;High-pressure pipelines;Large-diameter systems;Not suitable for flow regulation.
This type of valve features a robust structure and excellent sealing performance. It is driven by the linear motion of a rising valve stem and valve disc against the valve seat.
Check valves prevent backflow by allowing fluid to move in only one direction.
They are commonly used in piping systems to prevent reverse flow, which can damage equipment.
Control valves regulate fluid flow, pressure, or temperature by adjusting the valve opening.
These are essential in automated industrial systems for precise control.
Butterfly valves use a rotating disc to regulate fluid flow.
They are lightweight, cost-effective, and suitable for medium to large pipelines where space and weight considerations are crucial.
Safety valves protect systems from overpressure by automatically releasing excess pressure when it exceeds a preset limit.
They are critical for preventing equipment failure and ensuring safe operation.
Mechanical valves have extensive applications across various industries, including:
Valves play a crucial role in controlling the flow of crude oil, natural gas, and refined products in pipelines.
High-pressure ball valves, gate valves, and check valves are commonly used in this industry.
In chemical processing, precise control of fluid flow and pressure is essential.
Control valves, globe valves, and safety valves are used to ensure accurate chemical reactions and safe operations.
Power plants use valves to regulate steam, water, and fuel flow. They are essential for the efficiency and safety of boilers, cooling systems, and turbine operations.
These industries require high sanitary standards for fluid handling. Valves used in food and pharmaceutical production must be easy to clean and resistant to contamination.
Stainless steel control valves and butterfly valves are widely used in these sectors.
