1. The V-Smart™️ valve is a sliding sleeve, injection control valve machined from all 304 stainless steel components, conforming to NSF-61 standards, for deep well flow control and is hydraulically actuated by an above ground hydraulic power unit (HPU).

2. The valve sits above the bowls of a pump, either line shaft or submersible type, and is submerged below the static water level or maximum expected draw down level during pumping operation. The valve maintains a variable back pressure in the drop pipe to maintain well surface pressure at a safe margin above atmospheric pressure to prevent cascading water and air entrainment, while providing flow control into the injection well.

3. The valve maintains a minimal overall external diameter, as compared to other downhole control valves, enabling the valve to be located within smaller well casings, as small as 8” internal diameter.

 

• Allow for V-Smart™️ valve speed to be customized to site specific conditions, enabling finite control of the rate change per hydraulic unit open/closed command pulse.  This smooths out the action of seeking a set point, eliminating the possibility of over-shooting the target, while maintaining a precise narrow dead-band operating range.

• The Hydraulic Power Units are constructed with Nema 3R, steel or stainless steel enclosures for pad, pedestal or wall mounting. HPU’s are powered with 120VAC, electric hydraulic pumps, with temperature activated fan ventilation and a front-mounted, lockable access door. HPU’s include internal door-mounted, Hand-Off-Auto selector switch, Pump Start – Pump Stop push buttons, and V-Smart™️ Valve Open/Valve Closed push buttons. Indication lights are provided for HPU Power On, HPU Pump Running, V-Smart™️ Valve Driving Open, V-Smart™️ Valve Driving Closed, V-Smart™️ Valve Full Open Position, and V-Smart™️ Valve Full Closed Position. The unit includes solenoid control of the opening and closing of the V-Smart™️ valve, pre-set and adjustable hydraulic operating pressure, independently adjustable valve operating speed controls in both open and closed directions of travel, local and remote indication of valve full open and full closed positions, hydraulically locked system to maintain a fixed valve position in the absence of open or closed commands, (3) 3,000 psi oil-filled pressure gages, mounted inside the inner door to show output pressure from the pump and output pressure on both individual hydraulic hoses leading to the V-Smart™️ valve, 3 gallon oil reservoir with sight gage and 10 gallons food grade mineral oil (shipped in separate container for filling oil reservoir on-site).

V-Smart BIC-V Borehole Injection Control Valve™
Technical Overview – System Operation with Hydraulic Power Unit (HPU)

1. The V-Smart™️ valve is a sliding sleeve, injection control valve machined from all 304 stainless steel components, conforming to NSF-61 standards, for deep well flow control and is hydraulically actuated by an above ground hydraulic power unit (HPU).

2. The valve sits above the bowls of a pump, either line shaft or submersible type, and is submerged below the static water level or maximum expected draw down level during pumping operation. The valve maintains a variable back pressure in the drop pipe to maintain well surface pressure at a safe margin above atmospheric pressure to prevent cascading water and air entrainment, while providing flow control into the injection well.

3. The valve maintains a minimal overall external diameter, as compared to other downhole control valves, enabling the valve to be located within smaller well casings, as small as 8” internal diameter.

4. The valve has a full bore internal diameter, which allows for line shaft passage through the center of the valve, while maintaining a high flow capacity with ultra low head loss during production pumping.

5. The V-Smart™️ valve is hydraulically piston-actuated, without expanding bladders, therefore it can maintain a constant valve set point, regardless of flow or pressure changes in the system. Once driven to a set point, the V-Smart™️ valve will not move from position. This provides reliable and repeatable set point control with the ability to use a smaller valve with lower energy costs during pumping

6. The HPU is designed to pulse the V-Smart™️ valve open or pulse closed to drive the valve to a desired position for the preferred injection flow rate.

7. Two hydraulic hoses, conforming to NSF-61 standards run from the surface level HPU down to the valve. These are strapped to the column pipe by the contractor during installation.
