Gas valves are flow managing tools used to tackle and control the flow of gases like sour and natural gas, liquefied petroleum, oxygen etc. Gas valves are accessible in a various type of materials in plastic and metal that are suitable with the media controlled and pressure requirements.
Gas valves are used to balance the liquid propane or natural gas in heating systems. Gas valves differ in inlet/outlet size, Volume (cubic ft of gas) and type (standing pilot, slow opening, and step opening). Gas valves and controls must be equivalent to the heating system's fuel type. Gas valves must be converted to meet the system's requirements; therefore, the Liquid propane and natural gas conversion kits must be made available. After the verification of the system type, the system's capacity must be resolved. The selection of a normally open or closed gas valve is based on the calculated consumption frequency of the valve.

BUTTERFLY VALVES
A Butterfly valve is a type of quarter-turn whirling moving valve which is used to stop, regulate and start flow. A butterfly valve comprises of a disc which is set up on a revolving shaft. When the butterfly valve is completely locked, the disk entirely blocks the line.
Rotating the handle, either physically or with air-filled system, Butterfly valves rolls the plate perpendicular or parallel to the flow of the fluid. Butterfly valves can also be used for modulating the flow by rearranging the lever to get the preferred output flow.
The Key role of these Butterfly valves is to supervise the flow of liquids which pass through a section of pipe. Butterfly valves are majorly applied in waste treatment systems.
Types of Butterfly Valves:
Wafer-style butterfly valve :
The wafer style butterfly valve is created to preserve a seal resistant for bi-directional pressure dissimilar to stop any back-flow in systems developed for unidirectional flow. Wafer style butterfly valve comprises with a tightly fitting seal; i.e., gasket, O-ring, precision machined, and a flat valve face on the above and below sides of the valve.
Lug-style butterfly valve :
Lug-style valves have weaved enclosures at both sides of the valve body. This allows the Lug-style valves to fit into a system which uses two sets of bolts and no nuts. The Lug-style valve is positioned connecting two flanges using a separate set of bolts for each flange. This setup allows the other side of the piping system to be separated without distracting the other side.
A lug-style butterfly valve has a reduced pressure rating in such service where no further progress is possible. Lugged style valves are highly impervious to chemicals and solvents and can cope with the temperatures up to 200 °C, which makes it a resourceful formula.
Rotary valve
Rotary valves are prominently used in powder processing industries. Rotary valves, when closed, react precisely like a butterfly valve and is tight. But when the Rotary valves are in the rotation, the pockets permit release a specified quantity of solids which enables the valve appropriate for dosing bulk product by gravity. Such Rotary valves are normally of small size (less than 300 mm), pneumatically triggered and revolve 180 degrees back and forth.
ACTUATOR
A valve actuator is a motor-driven equipment that uses a power source to control the function of a valve. This power source can be pneumatic (compressed air), electric, or hydraulic (the flow of oil). An actuator normally is a mechanical tool that takes energy that is generated by electricity, liquid or Air and converts it into some kind of motion. Actuators prominently are utilized in manufacturing or industrial sectors and might be used in devices such as motors, pumps, switches and valves.
Common types of Actuators: Manual, Pneumatic, Hydraulic, Electric.
Manual Actuator : A manual actuator operates gears, levers or wheels to shift the valve stem and are usually operated by hand. Manual actuators are economical, normally free-standing and easy to operate. However, manual operation in some large valves is difficult and some valves may be situated in remote or unpleasant environments that block manual operations.
Electric Actuator : The electric actuator utilizes an electric motor to supply torque to function a valve. Electric Actuators are silent, harmless and power effective. Electric Actuators can also function on the batteries.
Spring Actuator : Spring-based actuators restrain a spring. Once any inconsistency is noticed, or power is lost, the spring is liberated, operating the valve. Spring Actuators can operate only once, without any modifications, hence are used for one time use such as emergencies.
One advantage for Spring Actuators is that they don’t need a high level electric supply to move the Valve. Spring Actuators can function from controlled battery power or can function naturally when all the power is drained.
Pneumatic Actuator : Air (or other gas) pressure is the power base for pneumatic valve actuators. The Pneumatic Actuators are utilized on linear or quarter-turn valves. Air pressure function on a piston or bellows diaphragm generating a linear force on a valve stem. As a substitute, a quarter-turn vane-type actuator generates torque to yield rotary motion to function a quarter-turn valve.
A pneumatic actuator may be scheduled as spring-opened or spring-closed, with air pressure surpassing the spring to allow the movement. A "double acting" actuator use air, applicable to various vents to pass the valve in the opening or closing route. A medial compressed air system can supply the clean, dry, compressed air required for pneumatic actuators.
Hydraulic Actuator : Hydraulic actuators transform the fluid pressure into flow and alike pneumatic actuators, the Hydraulic actuators are also utilized on linear or quarter-turn valves. A quarter-turn actuator generates torque to supply rotary movement to function a quarter-turn valve.
Most types of hydraulic actuators can furnish with protected features to an open or close valve under difficult situations. Hydraulic pressure can be provided by an independent hydraulic pressure pump. In few applications like water pumping stations, the process fluid can supply hydraulic pressure, however the hydraulic actuators ought to utilize materials compatible with the fluid.
