These valves are operated through external power sources, such as electric motors, pneumatic actuators, or hydraulic fluids, rather than manually. Actuated valves are essential in automated systems where remote control or automation of the flow is required.

Angle Valves

Designed with an inlet and outlet that form an angle, these valves are used for regulating flow in pipelines where space constraints or directional changes necessitate such a design.

Aspin Valves

Less commonly referred to in general classifications, Aspin valves might refer to a specific design or a brand-specific product focusing on specialized applications.

Ball Valves

Utilize a ball with a hole through its center to control flow. When the ball's hole is aligned with the flow, the valve is open; when rotated, it blocks flow. Ball valves are known for their durability and excellent sealing capabilities.

Blast Valves

Designed to protect against high-pressure blasts or sudden pressure changes, blast valves are crucial in systems susceptible to explosions or in protective shelters.

Butterfly Valves

Feature a disc that rotates around a central axis to open or close the flow path. They are compact and useful in applications requiring quick operation and moderate flow control.

Check Valves

Allow fluid to flow in one direction only, preventing backflow. They are critical in preventing reverse flow that could cause system damage or contamination.

Coaxial Valves

These valves have coaxially arranged ports and are often used in applications requiring precise flow control and high-pressure capabilities, such as in pneumatics and hydraulics.

Control Valves

Engineered to control process conditions by varying the flow size through the valve. They play a vital role in process industries for regulating parameters like pressure, temperature, and fluid level.

Diaphragm Valves

Use a flexible diaphragm to separate the flow of fluid from the operating mechanism. This design is particularly beneficial in sanitary applications or with corrosive fluids.

Flow Control Valves

Designed to maintain a constant flow rate, regardless of pressure variations in the system. They are essential in systems where precise flow regulation is necessary.

Gate Valves

Feature a gate-like disc that moves perpendicular to the direction of flow to start or stop the flow. Gate valves are used when a straight-line flow of fluid and minimum flow restriction are needed.

Globe Valves

Designed for throttling flow control. They have a spherical body and a movable disk-type element that adjusts the flow.

Knife Valves

Have a sharp edge to cut through slurry or viscous fluids. They are suitable for applications involving slurries or solids.

Contain a cylindrical or conical plug that rotates inside the valve body to control flow. They are simple and often used for quick shutoff.

Pressure Relief Valves

Automatically release pressure when a system exceeds its designed pressure limit, essential for safety in process systems.

Regulation Valves

Specialized control valves designed for maintaining a constant downstream pressure or flow rate.

Sampling Valves

Allow for the extraction of sample fluids from a system without interrupting the process or compromising the system integrity.

Solenoid Valves

Electrically operated valves that open or close when power is applied. They are widely used for controlling fluid flow in automated systems.

Each valve type is engineered to fulfill specific operational requirements, considering factors such as fluid type, pressure and temperature conditions, flow rate, and the need for precision control.
