Check valve

Jordan Valve has a large line of back pressure regulators that meet many different specifications and applications, from self-operated to air-loaded to pilot-operated. The sliding gate back pressure regulators achieve levels of performance, reliability, and accuracy that are not found in other valve designs.

In the normally closed position, upstream pressure is sensed underneath the diaphragm. As upstream pressure increases above the setpoint, the pressure of the service overcomes the spring force and begins opening the valve. This bleeds off the pressure on the upstream pressure side and maintains the constant upstream pressure.

To adjust a back pressure regulator you just need to adjust the screw at the top of the valve. You can tighten or loosen the screw.

The purpose of a repair on a backflow preventer is to return the assembly back to its original factory working specifications. The need for a repair can only be determined by conducting a field test on the assembly and knowing when the data indicates the backflow prevention assembly is in need of repair....

Back pressure regulators perform the opposite function of pressure regulators. A back pressure regulator is normally closed while a pressure reducing valve is normally open. Secondly, the back pressure regulator controls upstream pressure, while a pressure reducing valve controls downstream pressure. Other than that, the valves operate identically.

A back pressure regulator is a valve that maintains a defined pressure upstream of its own inlet. When fluid pressure at the inlet of the back pressure regulator exceeds the setpoint, the regulator opens to relieve the excess pressure. The back pressure regulator continually adjusts its position to keep the inlet pressure at the desired setpoint.

A back pressure regulator controls upstream pressure and is installed at the end of the line (unlike a pressure regulator that controls outlet pressure and is installed at the beginning of the line).

Our sliding gate back pressure regulators are ideal for steam, liquid, and gas media applications. Our team works with our customers to help achieve tangible results including lower operating costs, optimized performance, prolonged equipment life and higher productivity. You will see our back pressure regulators in a variety of applications including:

A back pressure regulator is a device that maintains a defined pressure upstream of its own inlet. In other words, it controls the inlet pressure while allowing any excess pressure to vent through the regulator.
