Cansco Well Control

Drilling Valves

Drilling gate valves are primarily designed to start or stop flow, and when a straight-line flow of fluid and minimum flow restriction are needed. In service, these valves generally are either fully open or fully closed.

Drilling check valves are designed to prevent back-flow during well control operations, and have an important role in well pressure containment assurance.

Hydraulic Gate Valves

The CANSCO DVH series hydraulic gate valve is a flanged through-conduit isolation valve built for the most demanding drilling applications. The CANSCO DVH combines the CANSCO DVM gate valve technology with double acting hydraulic actuator. Its one-piece solid slab style gate consistently delivers outstanding sealing performance throughout a wide range of conditions, bore sizes, and working pressures, including corrosive and abrasive fluid environments.

The slab gate design effects a metal to metal seal on the flow stream and its simple, straightforward design makes it easy to maintain low and high-pressure sealing situations where contaminates could pose a sediment problem. Primarily for sour gas and oil where resistance to Hydrogen Sulphide embrittlement is required, the DVH series is also suitable for other chemicals, products or hydrocarbons when H2S is present.

The DVH is fitted with a balancing stem to operate together with the double acting hydraulic actuator to provide reliable control through the entire stroke of the valve. A manual lock screw provides further well pressure containment assurance in the event of a loss of hydraulic operating pressure.

Manual Gate Valves

The CANSCO DVM series manual gate valve is a flanged through-conduit isolation valve built for the most demanding drilling applications. Its one-piece solid slab style gate consistently delivers outstanding sealing performance throughout a wide range of conditions, bore sizes, and working pressures, including corrosive and abrasive fluid environments.

The slab gate design effects a metal to metal seal on the flow stream and its simple, straightforward design makes it easy to maintain low and high-pressure sealing situations where contaminates could pose a sediment problem. Primarily for sour gas and oil where resistance to Hydrogen Sulphide embrittlement is required, the DVM series is also suitable for other chemicals, products or hydrocarbons when H2S is present.

The DVM series manual gate valves are standardised in design and have a high percentage of parts interchangeability to provide simple and efficient management and maintenance of gate valve fleets, and deliver optimal lifecycle management integrity.

Check Valves

The CANSCO DVC series check valve is an API 6A flanged non return valve built for the most demanding well control applications. Metal-to-metal sealing of the DVC poppet and seat is suited for high-pressure and high-temperature environments. The DVC check valve is primarily used for the prevention of back-flow in well control kill lines and kill manifolds and can be used with oil, gas, water, or drilling fluids.
