DESCRIPTION
The Rtork pneumatic Non-Return Valve also known as a check valve or one-way valve, is a type of valve that allows fluid or gas to flow in only one direction. It is designed to prevent backflow or reverse flow of the medium in a piping system. Here are some key features and functions of a non-return valve:
Directional Flow: The primary function of a non-return valve is to ensure that fluid or gas flows in one direction only. It allows flow in the desired direction while preventing backflow in the opposite direction.
Pressure and Temperature Rating: Non-return valves are available in various pressure and temperature ratings to suit different applications. It is important to select a valve that can withstand the specific conditions of the system it will be installed in.
Non-return valves play a crucial role in maintaining the integrity and efficiency of fluid and gas flow systems by preventing unwanted backflow. They are widely used in many industries and applications where unidirectional flow control is essential.
FEATURES
These NRV find usage in a number of applications such as oil, gas, water, refining, steam, and chemical industries. The non return valves can be availed in a choice of three kinds which include Extruded, forged and cast. These valves can pressures application of up to 10000 PSI with minimum pressure drop. The nonmetallic check valves are used in corrosive media and are resistant to alkalis, chemicals and hazardous gases. The special design also ensures high discharge with low friction. Port size: G1/8 to G1 -Assists in complying with safety regulations -Tamper proof -Compact and safe design -Low pressure drop -Automatically resets after failure correction -High corrosion resistance -High air pressure rating
