CHECK VALVE

Description of CHECK VALVE

All the retention valves (also known as non-return valves, anti-flow valves or check valves) completely shut off the flow of a fluid in one direction but allow it to continue to flow in the other.

This type of valve is used in those cases in which it is desired to allow the discharge of irrigation while maintaining the pressure of the service pipe. They are usually installed in pipes that are part of pumping systems and seek to avoid water hammer.

From Mundoriego We offer you different types of check valve:

All the PVC check valves They are made of PVC-U. They are highly resistant to inorganic chemicals, are easy to install and easy to maintain. They can be used both vertically and horizontally. PVC check valves are available with two types of union, socket and female thread. They also have different sizes in diameter (from 20 to 110 mm) and thread (from RH 1/2 "to RH 3").

All the brass check valves withstand pressures up to PN-16 bar and can conduct flows ranging between -10ºC and 90ºC. They are indicated for use with both air and water. They feature a conical shutter closure. These check valves are available with different thread diameters from RH 3/4 ″ to 2.1 / 2 ””.

All the rubercheck ductile iron check valves They have two discs that open when the water exerts pressure on them and close when the water stops circulating. These valves can be installed both vertically and horizontally. They withstand pressures up to PN16 and temperatures up to 120ºC. These valves are available in a variety of nominal diameters from DN50 to DN300.

All the check valves system A / C sight glass They are installed in those places where you want to prevent the flow from backing off, protecting irrigation equipment from possible water hammer. Thus, this valve has three functions: avoid water hammer by stopping pressure waves; emptying of facilities in the discharge area; and backflow after operations such as filtrations and injections of chemicals. These check valves are aimed at the management and treatment of water in both irrigation and industry. They are made of PVC and have three closing systems: free clapper, self-closing and self-closing visor. On Mundoriego We offer you system A / C sight glass check valves with nominal diameters ranging from DN80 to DN250.

All the chemical check valves They have a high resistance to wear caused by chemical substances. These valves have a body made of glass-reinforced polypropylene, a combination that ensures resistance to chemical agents used today in both industry and agriculture. It can work with a pressure up to 20 bar. for more enter here irrigation valve.
