DEMCO Series DT/DB Gate Valves are recognized for their quality design, rugged dependability and corrosion resistance, particularly for use in waterflood and CO2 applications.
DEMCO Aluminum Bronze and Stainless Steel Valves and Accessories are designed especially for the demanding requirements of corrosive CO2 injection and waterflood applications in the enhanced oil recovery market.
Features and Benefits:
- In-line field reparability-bonnet easily removed for inspection/replacement
- Corrosion resistant materials are standard, body and bonnet materials as well as all internal wetted parts comply with NACE RP-0475
- Rising stem design, the handle moves up and down on the bonnet providing visible aid to determine whether the valve is open or closed.
- Superior abrasion resistance, Buna-N elastomer encapsulated seats also provide an excellent deterrent to abrasion.
- Four ring stem packing set, preventing leakage into the stem journal and outside the valve
- Non wetted stem thread design, preventing stem seizure and assuring long trouble free valve performance.
- Accessories, Ball check valves, flow tees and strainers are available to complete requirements for an entire injection assembly.

Features and Benefits
- In-line field reparability, the bonnet easily removed for internal parts inspection and/or replacement
- Heavy duty roller bearings, heavy duty stem roller bearings reduce torque on 4 inch (100mm) and larger valves.
- Floating slab gate design, providing a tighter pressure responsive seal
- Unique, abrasion resistant, one-piece seat design
- Locking seat alignment, the seat assembly is engineered with a metal “lock shell” that aligns the seat in the bottom of the valve.
- Body wear rings-absorbing erosive wear that can damage the body around the seat bore area.
- Rising stem design-indicates gate position.
- Replaceable stem packing-without removing the bonnet from the valve.
- Flow cleansed design, prevents the valve from “sanding up”.
