Double Plate Check Valves
At GTM Process Valves, we offer, among other products, double plate check valves – their applications are incredibly diverse and they perform well in various systems. These are vital components commonly installed in hydraulic, heating, or compressed air systems. Their primary function is to secure and regulate the flow of water, air, and other liquids or gases passing through the network. They ensure the correct and reliable operation of installations even over many years.
In our industrial valve store, we provide double plate check valves with a sandwich connection, available in diameters ranging from DN50 to DN600, and operating within pressure ranges from PN10 to PN25. These valves are sourced from manufacturers such as GTM Process Valves, Socla, and Ebro Armaturen.

Double Plate Check Valve – characteristic
The double plate check valve belongs to a broad group of check valves used in pressurized installations. Their task is to ensure unimpeded water flow in one direction and effectively block the flow in the opposite direction. Despite their relatively simple construction, check valves are highly reliable installation components. They guarantee the proper operation of the entire network, safeguarding the system against serious breakdowns and protecting pumps from mechanical damage. Additionally, double plate check valves also eliminate the risk of leaks in the installation.
Types of Check Valves
Check valves comprise a vast group of elements that can be effectively utilized in various installations. Double plate check valves stand out as one of the most popular types. Among other variants are ball check valves, globe check valves, diaphragm check valves, and swing check valves. Each type differs in construction and general purpose, although their operational principle is quite similar.
Regarding double plate check valves, their distinctive feature is the closure assembly consisting of a double plate with a return spring. They have a compact design and can function in both horizontal and vertical pipelines, typically installed between flanges.
Double Plate Check Valve – Applications
Double plate check valves find application in industries such as the chemical industry, energy production, heating systems, wastewater treatment plants, and water treatment. Because they are constructed from highly durable materials, they can be easily used in very demanding environments.
The double plate check valves available in our store have been designed to operate in challenging and unfavorable conditions. They are crafted from materials such as gray cast iron, ductile iron, and stainless steel.
