Shafer™ Hydraulic Actuators

Shafer valve actuators serve a variety of markets: oil and natural gas pipelines (including offshore, subsea and natural gas distribution), processing facilities, and mining slurry operations.

Shafer SH-Series

The SH-Series actuator is a helical spline gas-over-oil actuator. This double-acting hydraulic actuator is perfect for a variety of small sized valves (2” to 8”) for gas pipeline services.

Shafer RV-Series Rotary Vane Hydraulic Valve Actuator

The RV-Series actuator is specifically designed for pipeline applications and is typically powered by natural gas using gas-over-oil technology.

Shafer L-Series Gas Over Oil Valve Actuator

The L-Series is well suited for gate valve applications on crude oil or products pipelines. The Actuator are typically powered hydraulically or by nitrogen pressure vessels.

Shafer Electro-Hydraulic Power Unit

Designed to take advantage of the available gas pressure in the pipeline. Suited for applications actuator power source is from natural gas pipeline, alternate actuator power source to gas over oil applications where 120 VAC, single phase electrical power is available, and for new or existing equipment. Existing Actuator with gas over oil type power supply may be converted, in the field, with an electro-hydraulic power unit.

Shafer Emissions Controlled Actuator Technology (ECAT)

This product applies progressive technology to prevent emissions but also uses Emerson’s proven Shafer technology and controls to stroke valves under the most demanding conditions.
