What is back pressure valve?

What is back pressure valve?

A back pressure valve is a type of control valve that holds pressure on production vessels such as separators, treaters, and free water knockouts and releases upstream pressure when a designated set point is reached.

Is a back pressure valve the same as a check valve?

Back pressure is when there is upstream flow pressure in the system. In other words, the pressure at the check valve outlet port is higher than the inlet port. Check valves without springs require backflow and the resulting backflow pressure in order to close.

Where should a back pressure valve be installed?

Generally, the back pressure valve can be installed anywhere in the discharge line, provided there is some downstream pressure at the dosage point. If there is no downstream pressure, the back pressure valve should be installed at the dosage point to prevent siphoning and drainage of the chemical line.

What is BPV in oil and gas?

Back pressure valves are installed in the tubing hanger to hold pressure from below during the following operations: The BPV holds pressure from below to isolate well pressure, but allows flow from above to permit killing of the well if necessary in an emergency, i.e., the BPV functions as a check valve.

What is back pressure in PSV?

Back pressure is the pressure on the outlet of the pressure relief valve. There are two types of back pressure: Superimposed back pressure. Superimposed pressure is the pressure in the discharge header before the pressure relief valve opens.

What is tubing hanger in oil well?

​ A tubing hanger is a component used in the completion of oil and gas production wells. It is attached to the topmost tubing joint in the wellhead to support the tubing string.

What is a two-way valve?

A 2-way valve is a straightforward device with two openings, one for inlet and the other for outlet. These chilled water control valves simply regulate the flow of the fluid through them by varying the size of the valve opening, and can work as on/off devices.

Is a check valve a two-way valve?

The check valve is only a one-way opening and closing valve that prevents the backflow of fluid media on various pipelines or equipment. There are many types of check valves: (1) Spring type: the liquid is from bottom to top, relying on the pressure to push up the valve flap controlled by the spring.

What is back pressure in a pipe?

Back pressure (or backpressure) is a resistance or force opposing the desired flow of fluid through pipes, leading to friction loss and pressure drop. Similarly, bending or other operations on a pipe (such as a stock car exhaust system with a particularly high number of twists and bends) can reduce flow rate.

What is a back-pressure valve?

Back-Pressure Valve installed in tubing hangers BPV is commonly used during the nipple down and up of the drilling BOP stack, nipple up or down of Christmass trees, test the Christmas tree (2-way check valve), and during the replacement of the master valve. NB: A two-way check valve is designed to fit the same profile as the BPV.

What is a two-way check valve used for?

NB: A two-way check valve is designed to fit the same profile as the BPV. It holds pressure from both directions while allowing equalization when required and is used to test the tree and BOP assembly.

How do you remove a back pressure check valve?

The rod is lowered into the slot on the top of the valve and continuing the right-hand (clockwise) rotation removes the valve. Tagged Back-Pressure valve, BPV, Cameron Type H BPV, Check Valve, one-way check valve, Petroline ABC BPV, tubing hanger, Tubing Hanger Flange, two-way check valve.
