Exploring Mechanical Valves

Explore a comprehensive selection of mechanical valves engineered for industrial automation, pneumatic systems, and machine control applications. From roller lever valves to push button and foot pedal designs, these mechanical valves deliver precise manual or mechanical control over air flow, ensuring reliable performance in diverse operational scenarios.

A mechanical valve is defined as a valve operated manually or via mechanical force, encompassing various types such as:Hand-pull valves、Push button valves、Speed control valves、Quick exhaust valves、Foot valves、Hand sliding valves、Check valves、Flow control valves、Shuttle valves, etc.

Its normal operating pressure ranges from 0 to 10bar, and the operating temperature spans from -5 ℃ to 60 ℃.

★ Hand Lever Valve

★ Foot Valve

★Flow Control Valve

★Quick Exhaust Valve

★Ball Valve

Hand lever valve is a key manual flow control component in diverse systems, offering precise regulation, durability, and no external power need. It works via a handwheel adjusting the stem and disc, with a globe-shaped body minimizing turbulence and pressure loss for high-pressure/temperature use.

★C23-06A/B/H 5/3 Toggle Valve

★4R/3R Series Hand-Draw Valve

★TSV/4H Series hand-pull Valve

★HV Series Hand-Switching Valve

A foot valve is a critical one-way check valve for water and fluid pumping systems, installed at the start of the suction line (submerged in tanks, wells, or reservoirs) to prevent backflow, improve efficiency, and protect pumps. 

It works via a vacuum from the running pump that opens the valve, while a weighted/spring-loaded flap closes automatically when the pump stops—keeping the line primed, maintaining pressure, and eliminating repeated priming needs. 

Autoair offers specialized pneumatic foot valves:

★4F Series Foot Valve

★4FV Series Foot Valve

★SK/ST/SH Series Foot Valve/Manual Valve

An air push button valve is a compact, manual pneumatic component that controls compressed airflow via physical button actuation, essential for safe, efficient manual control in industrial systems. 

It converts manual force into pneumatic signals to start/stop airflow to cylinders, actuators, or valves, operating mechanically with no electricity required.  

Autoair offers specialized pneumatic air push button valves:

★JM Series Mechanical Valve

★JMJ Series Mechanical Valve

★MOV Series Mechanical Valve

★MV522 Series Control Valve(5/2 Way)

★CM3/S3 Series Control Valve（3/2Way）

A check valve (or non-return valve) is an automatic mechanical component that regulates fluid flow in systems, allowing one-way movement while blocking reverse flow to protect equipment and maintain efficiency. 

It operates without external control—opening under forward pressure and closing via gravity, backflow pressure, or internal mechanisms .  

Autoair offers specialized pneumatic check valves:

★CV Series Check Valve

★KA Series Check Valve

A flow control valve is a key component in fluid systems, enabling precise regulation of flow rates to optimize performance, boost efficiency, and protect equipment across industrial, commercial, and residential applications. Unlike simple on/off valves, it offers variable control to adjust fluid (liquid or gas) volume/velocity, operating by altering orifice size—narrowing to reduce flow or widening to increase it—with manual (handwheel/knob) or automated (electric/pneumatic) actuation.  

Autoair offers specialized pneumatic flow control valves:

★ASC Series Accurate Type Flow Control Valve

★RE Series Flow control Valve

★KLA Series Check Valve

The hand sliding valve is a versatile and reliable component in fluid control systems, designed for manual operation to regulate or stop the flow of liquids or gases. With its straightforward structure and durable performance, it is widely used across industries where simplicity, direct control, and independence from power sources are critical. This guide explores its design, functionality, applications, and key benefits.

★HSV Series Sliding Valve

A shuttle valve, also known as a double-check valve or priority valve, is a critical fluid control component designed to manage flow direction between two input ports and a single output port. Its core function is to automatically direct fluid (liquid or gas) from the higher-pressure input to the output, while blocking flow from the lower-pressure input. This makes it ideal for systems requiring redundancy, safety backups, or selective flow routing.

Autoair offers specialized pneumatic shuttle valves:

★ST Series Shuttle Valve

★QE Series Quick Exhaust Valve

A quick exhaust valve is a specialized pneumatic component designed to optimize the performance of pneumatic systems by accelerating the exhaust process of compressed air. It plays a critical role in enhancing the speed, efficiency, and responsiveness of pneumatic actuators, such as cylinders, by bypassing the need for air to flow back through the entire system during exhaust.
