Oliver Valves offer both sampling valves and injection valves. With our innovative designs, you'll easily be able to sample the process stream, and inject chemicals and other media into the process stream. With a variety of different nozzles, our sampling and injection valves can directly integrate into any new or existing Oil, Gas and Petrochemical project.

Overview

?

Sampling Valves Details:

Sampling the process stream can be accomplished with our valves, where a sample can be taken even at full system pressure directly from the process line. The product allows double isolation from process for safety. The orientation of the sample nozzle is fixed at the assembly stage and can be specified to suit the application.The flanged body drop forging is machined to ANSI B16.5 flange dimensions with the forged body section incorporating two isolation valves and one bleed valve.

A custom designed sampling probe extends from the flange connection into the process media for correct removal of the sample. If projections into the process line cannot be allowed the valve can be supplied without a probe. Sampling valves can be provided with either a single flange connection and screwed connection or double flange connections.

Injection Valves Details:

Injection of chemicals and other media onto the process stream can be accomplished easily with our injection valves. The valve inlet houses a one way check valve which opens for injection and goes normally closed to eliminate process fluid outflow. The orientation of the injection nozzle is fixed at the assembly stage and can be specified to suit the application. The flanged body forging is machined to ANSI B16.5 flange dimensions and incorporates two isolating valves and a bleed needle valve.

The injection probe extends from the flange connection into the centre of the process stream for the correct positioning of the injection media. Injection valves can be provided with either a single flange connection and screwed connection or double flange connections. The N Type double block and bleed with injection facility is also available.

3D Models are available upon request.

Nozzle Technical Information

PROBE LENGTH:

This length is manufactured to suit customer requirements for the correct positioning of the injection orifice, up to a maximum length of 24". The position of the injection orifice can also be rotated at assembly to suit orientation relative to the valve handles.

PROBE MATERIALS:

The standard material is 316 stainless steel but other materials can be used to suit customer requirements.

INJECTION NOZZLES:

The standard orifice is a 0.125" (3mm) diameter hole but other arrangements can be accommodated including swirl pattern spray nozzles to improve dispersion of the media.

CHECK VALVE:

This poppet type spring return valve has a Viton soft seat, and offers bore sizes of 10mm (CV2.0) or 12mm (CV4.6) or 16mm (CV7.2). Alternatively flange to flange styles of 6mm (CV2.0) max or 10mm (CV2.0) (maximum temperature 120 C) can be furnished. For Methanol injection specify Kalrez 'O' ring material for check valve seat.
