These valves are used for intermittent or continuous flow applications

3Ply MONEL bellows for durability and reliability

Filling the bellows with silicon fluid protects the bellows from hydrostatic forces (pressure) in the well by forming a hydraulic

barrier. This silicon fluid also minimizes the vibrations and chattering which prevents the seat from any damage

MONEL or Tungsten Carbide seat can be replaced easily for servicing

The reverse flow check valve helps to avoid costly work over procedures

Double check valves can easily be added for greater protection and reliability

The maximum travel stop feature eliminates the risk of bellow stacking and increases their cycle life

Operating efficiency is improved by the large dome component

Valves are available in any material, primarily Stainless steel or Nickel - Copper Alloys

These valves can be coated if necessary to meet the most demanding applications

Applications

RCF-2 / RCF-BL1

Common Formulas Used in Gas- Lift Design

TV Temperature of Value

TCF Temperature correction factor (N2)

R Ap/Ab (Ratio of port area to bellows area)

DPC Casing pressure at depth – casing pressure at surface

Pt Tubing pressure ar transfer point

Pto Tubing pressure required to open valve

Psc Closing Pressure at surface

Pvc Closing pressure at depth[Pvc=Psc + DPC]

OP Opening pressure at depth [OP=(Pvc-Pt*R) / (1-R)]

Pso Surface opening pressure [Pso=OP-DPC]

Pd @ F Bellows pressure at base temperature [Pd @F=TCF X Pvc]

Ptro Test rack opening pressure[Ptro = (Pd @ F) / (1-R)]

Force Balance Equations for Gas- Lift Valves

R=AS/ Ab= [( OP – Pvc)/ (OP – Pto)]

Where: Ab = Area of bellow, sq in.

As=Area of seating diameter, sq in.

Ptro = [Pvc/(1-R)]

OP = [(Pvc-(R x Pto)) / (1-R)]

Pto = [(Pvc-(OP x (1-R))/(R) ]

Pvc = [OP – (R x (OP-Pto))]

Note:

For Square –edged seats, diameter of seating area = [(diameter of port, in) + 0.006in.]

For tapered seats, dia of seating areas =[ (diameter of ball, inc) x (since seat angle)]

FLUID GRADIENT AND PRESSURE FORMULA

Fluid Gradient Versus Slurry Density

(Hydrostatic Pressure Exerted by Fluid / Sand Mixtures)

To properly operate a tool in the presence of a sand- laden slurry, calculated the hydrostatic pressure exerted by a column of this slurry. The following provides fluid gradient factors needed for this calculation, based on the true density of the sand being 22.144 lb/gal.

Density of Sand/ Fluid Slurries:

Lb/gal slurry = (MW + PSA) ÷ [(0.0456 x PSA) + 1]

Where:

MW = lb/gal of fluid

PSA = Pounds of sand added per gallon of fluid
