Standard two way switch, similar to a three way switch in electrical.I will be using this as a shut off valve to an air mist lubricator. Needing only one of the two outlets, unused one will be plugged.The supplied Push-To-Connect fittings are 1/4" NPT x 3/8" OD hose.Good pricing for this product.

First impressions, this is a well made. Quality manufactored with a great fit and finish. This is one hefty block of a valve. Very robust. I also appreciate the large and easy to use button switch, makes use even nicer. You also get pretty much everything you need to hook it up and use it. So far it works as it should, no complaints. Will update this if anything changes. One star off for NO instructions, seems they don't care about showing their customers how to use the product.Overall, good valve, okay price, would recommend.

Add a pneumatic cylinder, an air supply source, 8mm pneumatic tubing, and some hardware, for the makings of a can crusher.This two-position controller has one input port, two output ports (one for each control stick position to make the pneumatic cylinder push and pull) and two exhaust ports. The controller comes with 3 pressure fittings and 2 exhaust fittings. A common configuration for use as a can crusher controller is "push" to compress the can then "pull" to return the pneumatic cylinder piston to its home position. Some configurations will use the escaping air from the appropriate exhaust port to eject the crushed can as the piston is returning to its home position.The controller kit also comes with a roll of Teflon tape. The handle of the throw switch is unscrewed for shipment. Some assemblers recommend not using Teflon on the pressure fittings because if improperly applied, pieces of the tape can come loose over time and cause an air valve to malfunction which requires parts of the controller to be disassembled in order to fish out bits of Teflon tape. Replacement of Teflon tape with pipe thread dope is recommended.The controller is made of appropriate materials and the 2-position joystick works as one expects without excessive play or being too stiff. The fittings did not leak after installing on the body of the controller. There are 3 thru mounting holes on the body of the controller to firmly attach the controller housing onto a work surface or backing board.

The YAOJING 3H210-08 3-Hole and 2-Position Control Valve is a pneumatic valve that serves as a versatile component for controlling airflow in various pneumatic systems. It is typically used in industrial applications such as automation systems, machinery, and other devices requiring control of compressed air. Below is a review based on its features, pros, and cons:Pros:Versatile Control Function: The 3H210-08 model features a 3-hole and 2-position design, which allows for precise control over the flow of compressed air. This design is especially useful for systems where directional control of airflow is essential, such as in actuators, cylinders, and other pneumatic components.Manual Control: The valve is equipped with both hand-pulled and hand-pushed control mechanisms. This offers flexibility for users to engage the valve manually, which is ideal for situations where automation or remote control isn't necessary, and manual operation is preferred for safety or simplicity.Durability and Reliability: The 3H210-08 valve is built to withstand the rigors of industrial environments. It is designed for longevity, and the materials used in its construction are durable, making it a reliable choice for various pneumatic applications, especially in harsh environments.Easy Installation: The valve comes with a standard 1/4" threaded connection, which makes installation straightforward and compatible with many pneumatic systems. This ensures compatibility with a wide range of components, reducing setup time and the need for special adapters.Cost-Effective: Compared to other pneumatic valves, the YAOJING 3H210-08 offers good performance at an affordable price point. For users needing a basic control valve for a pneumatic system, it provides value without a high investment.Compact Design: The compact size of this valve makes it suitable for applications where space is limited, making it a good choice for small systems or crowded environments where space-saving is essential.Cons:Manual Operation: While the hand-pulled and hand-pushed controls are useful, the manual operation may be a disadvantage for automated systems that require remote control or integration with sensors and actuators. If you require automation or more advanced features, this valve may not be the best choice.Limited Pressure Handling: The 3H210-08 valve may not be suitable for extremely high-pressure applications, as its design is primarily intended for standard pneumatic systems. Users requiring valves for higher-pressure systems may need to look for models that are designed for such use.Basic Functionality: This valve is a basic mechanical control valve, meaning it lacks the advanced features found in electronic or solenoid-controlled valves. If you need advanced controls like proportional flow or variable positioning, this valve would not meet those needs.Noisy in Operation: Some users may find the mechanical action of the valve (manual hand control) to be noisier than solenoid-operated valves. If low noise operation is a concern, this may not be ideal.Overall:The YAOJING 3H210-08 3-Hole and 2-Position Control Valve is a simple, durable, and cost-effective pneumatic valve that excels in manual control applications. It is best suited for basic pneumatic systems where manual operation and directional control of airflow are required. The valve is reliable, easy to install, and offers good value for money. However, it may not be ideal for highly automated systems, high-pressure applications, or users needing advanced control features. For straightforward, manual pneumatic control, this valve performs well and offers lasting durability at an affordable price.
