All-Electric Surface Actuator

Remote control and predictive condition-based maintenance of surface valves

Reduce opex, capex, and environmental impact.

Hydraulic Actuators

Recommended for large-bore and high-pressure valves

Used in high-thrust applications when there is no gas source or when the well gas is too sour.

Pneumatic Diaphragm Actuators

Built to the industry’s highest standards

Rely on a simple design and operating principle.

Pneumatic Piston Actuators

Used in air operated systems

Perform sequenced closure during shutdown operations.

Actuator Accessories

Complementary products

Adapt to existing actuators in the field or installed on new manufactured actuators.

Choke Valves



For all heavy oil recovery operations, including SAGD and CSS.

Compact Insert-Retrievable Chokes

35% smaller, 45% lighter

Achieve total vertical access for insert retrieval.

Insert-Retrievable Chokes

Time-tested designs

Retrieve the trim, actuator, and retention mechanism to surface.

Nonretrievable Chokes

800 installed to date

Mount to a subsea structure or incorporate into retrievable FCM or choke bridge.

Frac Valves

Frac Valves

High-pressure valves to improve fracturing efficiency

Maximize corrosion and erosion protection, streamline maintenance, and minimize NPT and related costs.
