There is no difference between check valve and NRV, both are same
check valve are used to make flow in one direction and is normally sprig loaded to ensure a positive seal with greater delta non return valve are normaly used on fluid pipe ,, to make flow in uni direction,,, that the fluid canot be return back
The term cock and valve are used interchangeably in the English language. The term cock has in large been replaced with valve with no functional difference between the two.
valves are use in four stroke engine, and ports are use in two stroke engine.
MOV is Motor Operated Valve which operate by motor but , ZV operated by instrument air or hydraulic pump in case of manual operation Thank you,
The Globe valves are generally used to control the flow rate and ball valve used for open /close purpose only.A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it.

There is no difference
i believe the reflux valve is just a type of check valve, the flapper type.
foot valve is the same type of valve with check valve but the application is on the section side of pump for priming purpose
A dual check valve is similar to a double check valve in that it is a mechanical backflow preventer consisting of two independently acting, spring-loaded check valve.
A check valve allows for flow in one direction and a gate valve is used for positive shut off and a globe valve is used for throttling
A check valve allows for flow in one direction and a gate valve is used for positive shut off and a globe valve is used for throttling
whats the difference between soleniod valve and control valve
A check valve allows a flow only in one direction. It drops down to prevent a backwards flow. A butterfly valve allows control of the speed of the flow by regulating how much of the flow is unblocked.
none
no you cant
A non return valve is used mainly on fluid pipe, which uses gravity and the fluid to close it. A check valve is normally spring loaded to ensure a positive seal and will need a greater delta P to open. Also check valves are normally used with gas.
