SkoFlo pressure independent chemical injection metering valves allow one pump to be shared by several injection points, thereby reducing facility costs and maintenance costs. As an added benefit, SkoFlo valves are maintenance-free; while pumps may require several seal changes over the life of the project.
SkoFlo Surface Back Pressure Regulators (BPRs) are simple and robust anti-siphoning devices that creates back pressure in chemical injection umbilical lines to prevent uncontrolled delivery of chemicals into production wells. The BPR is a purely mechanical device which requires no electrical power.
Upstream and downstream pressure fluctuations create a net force on the patented pressure balanced piston, which is countered by a spring force to maintain constant flow.
Accurate Flow Delivery
Pressure‐balanced piston provides instantaneous means of control at different injection points from a common line that is more tolerant to debris and fluid filming. No pneumatic or electric power sources required for control.
Accumulated debris results in a net force on the piston that instantaneously lifts the pin slightly from the seat, passing the debris through the outlet. This net force is countered by the spring force that returns the piston to its balanced flow rate position.
