An angle valve, also known as a diaphragm valve, is a semi-piston valve with a cylinder rotor acting as a piston. The seat is placed at an angle to give the most effective flow even when not completely sealed. The angle is set to allow the most flow of gas in a fully closed position. In order to open the valve, the angle must be increased or decreased to match the angle of the valve seat.

The angle valve was first used on many steam locomotives in the 1800's. They are still used in many steam locomotives today. The diaphragm design is very effective and reliable for high-pressure applications.

Diaphragm angle valves are used in many different applications and some will say they are more efficient than the rotary lever. They are also used on diesel engines. They are used in brake applications and sometimes act as a speed controller. There are many reasons that angle valves are used in a variety of industries such as oil & gas, chemical processing, pharmaceuticals, power generation, water treatment and others.

A diaphragm is similar to a baby gate. It can be controlled electronically to open and close the valve according to the flow of gas. These valves are used with hydraulic systems to increase or decrease the flow. One of the benefits of angle valves is that they do not require a control box or key to open and close the valve. This feature makes them more useful for automatic control applications.

There are many applications where a diaphragm angle valve would be beneficial. They are usually used as a safety device to reduce the chance of a catastrophic gas leak. The valve is usually closed by locking or turning off the flow. If the pressure is too high or the flow rate is too low, then this valve will cause an alarm to sound and shut off the flow. If the valve remains closed then it causes a potentially catastrophic gas leak.

The angle valve can be a valuable addition to the HVAC system. They can be installed with any type of intake port, including PVC, poly pipe and many others. They are usually available in a kit to make the installation process fast and easy. You can either choose a straight angle valve or a curved angle valve. A curved angle valve has more flexibility and can fit many different intake ports and configurations.
