Unlike traditional check valves, gate valves have very low flow resistance, thanks to the straight-through design of the wetted area. Stainless steel is also corrosion-resistant, and will not leach into the medium it passes through. It can be used in areas where corrosive fluids are present, and it can be used in drinking water. Despite its low resistance to fluids, the valve is relatively easy to maintain. Before installation, clean the sealing surface and cavity of the gate valve, and tighten the packing.
The valve seat is attached to the body of the valve by a screw and can be either rising or falling. When fully opened, a gate valve exposes the stem of the gate. A sealing gland in the body compresses the packing and creates a tight seal. A rising stem gate valve is suitable for above-ground installation. The valve is not recommended for use with corrosive liquids. It is advisable to install a gate valve with a high-flow capacity.
The stem of a gate valve is attached to the body of the valve. The rising stem is connected directly to the gate. This is a visual indication of the valve's position. The nonrising stem is threaded into the body and has a pointer at the top. It is best suited for applications that have little vertical space and do not want to scrape. If a rising stem is necessary, it should be installed with the valve's body.
A gate valve has two parts. The body is the largest. The valve's spindle is attached to the body. The body contains two springs which act as hinges. The spring is an internal component that provides a tight seal. A spherical valve is more efficient than a lever valve. A pressure-sensitive model is a type of ball valve. This design also provides higher pressure than the other type. The bonnet is made from steel.
A gate valve has two types of bonnets: a non-rising stem and a rising stem. The rising stem is used in high pressure service. In a non-rising stem, the stem is stationary. The non-rising stem has a single disc. During a closed valve, the disc and the stem move up and apart. The media is then allowed to pass through. The fully open gate valve provides minimal resistance and little pressure drop.
A gate valve has two types of seats: the rising and the falling stem. The rising stem is fixed to the gate and rises and falls together with the valve. The rising stem is fixed to the gate, while the sinking one is mounted between two seats. The rising and the falling stem are fixed together. The roses and falling stems are connected to each other by a threaded rod, which is threaded into the valve.
The wedged gate is the most common type. It has two inclined seats. When the gate is closed, it will not stick to the seat. A wedge-shaped valve can be used for high-pressure applications. However, it is not recommended for use in corrosive fluids. Its flexibility allows it to withstand high-pressure conditions, such as high-temperature environments. The flexible wedge is a good choice for corrosive fluids.

How AND valve in pneumatic system operate?
It is similar to logic gate AND. One out put with two inputs. Output is true when both inputs are true the valve has two air inputs. Valve operates only when both the input air are present. Valve wont operate with any one air input.
