Valve, Choke, Taylor, RB Series, 4-1/16", R39, W/Rotork IQTF Actuator, 5000#

The RB Series Control Valve features several unique design characteristics that minimize

wear and maximize service life.

The nozzle and external sleeve trim is designed to contain turbulence and wear by

managing the flow into the nozzle and centralizing it into bore causing the flow streams to

impinge on each other. The valve body and outlet are protected from wear because the energy

conversion as a result of the pressure drop is concentrated in the trim cavity before flow enters the outlet.

This eliminates the typical wear problems in the valve outlet.

The Upstream and Downstream balanced sleeve design greatly reduces the breakway and

closing thrust requirements to lift the sleeve on and off seat as well as during stem travel

making the control stable and precise yielding better accuracy and repeatability.

Accurate Control - Multi-Orifice Nozzle design provides precise control over a wide range of flows.

Bolted Bonnet - A bolted bonnet prevents corrosion, cross-threading and galling of large threaded

connections. The design allows for simple assembly and disassembly.

Extended Mean Time Between Service - Robust design, application of hardened materials, and efficient flow

geometry results in maximum production potential and minimum service requirements.

Easy Maintenance - All Control Choke Valves are designed with special actuator mounting systems so the choke can be maintained without disassembly of the actuator and components or instrument connections.

High Turndown Ratio - Clean flow geometry, high capacity and accurate control means the valve is

suitable for both start-up and end-of field-life-process scenarios. In short, our control choke valves

offer a one-valve solution for the full process life.

Optional Features - Control Valves can have trims and actuators custom designed for specific

requirements. Such as special noise reduction trims, reduced port and maximum orifice trims for very

high pressure or minimum pressure loss for a declining field.
