What is a Lift check valve? A lift check valve is a type of check valve which is used to prevent fluid from flowing backward. If the fluid attempts to flow backward it is blocked. Lift check valves are one-way valves meaning they allow fluid to flow in one direction only. Lift type check valve is suitable for use in …

What is a dual check valve?  A dual check valve is a special type of check valve which is used to prevent reverse flow of fluid. This type of valve consists of two automatic, spring-loaded check valves that work together to prevent reverse fluid flow and thus prevent fluid contamination and damage to piping equipment like pumps. The dual check …

What is a wafer check valve? A wafer check valve is a type of check valve that has a butterfly or wafer-type disk used to open and close fluid flow. A wafer check valve has two ports that is the inlet and outlet port. The valve opens when the inlet side pressure becomes more than the cracking pressure. When the …

What is a spring check valve?  A spring check valve is a type of check valve used to prevent fluid flow from reversing direction. Spring check valves are one-way direction flow and they are automatic. Spring check valve manufacturers design these valves with one inlet and one outlet port. The spring check valve is also known as a spring non-return …

What is NRV valve? NRV valve in full means non-return valve. NRV valve is also known as a one-way valve or check valve. This is a type of valve that allows fluid to flow in one direction only. These valves work by opening when fluid flows forward but it closes when the fluid flows backward or when the fluid tries …

What is a double check valve? A double check valve is a type of valve that is used to prevent the backflow of fluid in water supply systems. Preventing the backflow of water helps to prevent contamination. A double check valve is made up of two check valves that are assembled in series. One of the check valves works even …

What is a non-return valve? A non-return valve is also known as a check valve. This is a valve that is used to prevent fluid from flowing backward in a pipeline. A non-return valve is also known as a one-way valve. This is because non-return valve manufacturers design these valves such that fluid flows in one direction only. Non-return valves …

What is a cryogenic globe valve? A cryogenic globe valve is a type of globe valve which is meant for use in very cold applications. These valves are mostly used by companies that work in compressed natural gas or liquefied natural gas for throttling, opening or closing fluid flow. Cryogenic globe valve manufacturers design these valves in a way that …

What is a Y pattern globe valve? Y pattern globe valve is a type of globe valve which is used to regulate, open and close fluid flow. These valves are also known as oblique pattern globe valves. The design of a Y pattern globe valve is such that the seat and stem are oriented at 45o degrees to the axis …

What is a steam globe valve? A steam globe valve is a type of globe valve which is meant for use in controlling the flow of steam. Steam globe valves are used for throttling, opening, and closing fluid flow. These valves are also used to control flow of steam pressure. Steam globe valves are used in different applications such as …

What is a stainless steel globe valve? Stainless steel globe valve is a type of globe valve that is made of stainless steel. This type of valve is meant for throttling, opening or closing fluid flow.
