Diyak Ltd’s 1″ and 1.1/2″ Wireline Retrievable Orifice Valves are used to control gas or fluid flow from either the annulus or tubing based on the porting of the side pocket mandrel. Orifice valves are used where pressure control is not necessary.
The valve is designed with a square edge orifice which, when properly sizes allows volume control when the casing and tubing pressures are known. An integral reverse flow check valve prevents reverse flow communication back through the valve.
These valves are available in either Stainless Steel or Nickel alloys for corrosion resistance in wells with high concentrations of H2S or CO2. Packing and elastomeric materials for the valve are available for standard service or special service to suit individual well conditions.
The simple design of the orifice valve allows for easy replacement of the packing and for rapid low-cost repair of components. The rugged, solid construction and quality materials provide for long service life.
FEATURES & BENEFITS:
Stainless steel or premium materials available.
Replaceable floating square edged orifice (Tungsten Carbide inserts are also available)
Flow capacity determined by orifice sizing.
Integral reverse flow check valve prevents reverse flow communication.
Temperature rating of 250°F (121°C) (Standard Service)
Standard Neoprene packing with other materials available.
Compatible with other manufacturers side pocket mandrels.
APPLICATIONS:
The Wireline Retrievable Orifice Valves are used to establish communication between the tubing and annulus during circulating, gas or fluid injection operations. They are utilized in single point injection continuous flow completions. These valves have no closing function and are commonly used to control stable injection at the operating valve depth.
