Scotch Yoke actuators Efficiency and long life Every Econ Scotch Yoke actuator is built to provide long end efficient service with minimum maintenance. The design, engineering and materials used in their construction ensure optimum performance even in the harshest environments. Econ Scotch Yoke actuators are available with symmetric yokes. A symmetric yoke provides more constant torque throughout - at both the break points and end positions. Symmetric Yoke Mechanism Spring to close Spring to open The center body s chromium plated alloy steel guide bar minimizes the transverse forces of the Scotch Yoke mechanism and ensures proper alignment of the piston rod. The enclosed weatherproof center body and end caps are sealed with O-Rings, which protect the actuator against water ingress. Econ s Scotch Yoke actuators have bidirectional pinion travel stops. Bidirectional travel stops allow for ±10 travel adjustment between 80 to 100. These travel stops help absorb impact loads associated with recommended travels speeds and prolong valve seat integrity. Air stroke Spring stroke 100 90 80 Spring stroke Air stroke Closed 45 Angular position Open Closed 45 Angular position Open Flexible configurations Econ Scotch Yoke actuators are manufactured in many different combinations of sizes, cylinder diameters, and designs. Both the double acting Fig. 7992 and spring return Fig. 7991 designs are available for installation on quarter turn valves such as ball, butterfly and plug valves. Scotch Yoke actuators are designed for use over a wide range of pressures or temperatures. Econ Scotch Yoke actuators are of modular design. A pneumatic or hydraulic cylinder can be attached to either side or both sides. With a large stock of finished and semi-finished components always available, actuators can be assembled and supplied with very fast and reliable deliveries.

Fig. 7991 Spring return - Fig. 7992 Double acting Control panels/cabinets Econ actuators can be provided with various control systems ranging from a simple setup, comprising a mounting plate with a filter-regulator and solenoid valve, up to complex modulating control systems and full PLC controlled hydraulic power units (HPU). Available options Performance specifications Manual overrides The manual override is an important requirement for many valve/actuator applications. In case that air fails, the user will be able to open or close the valve manually. Econ has a variety of override options available to meet any requirement. Available options include jackscrew or hydraulic manual override. We also offer solutions in Tank Reservoir Systems and Hydraulic Power Units (HPUs.) Jackscrew manual overrride (HW) Maximum allowable working pressure Hydraulic pressure: up to 135 bar (1,960 psi) Pneumatic pressure: up to 8 bar (120 psi) Torque output Double acting (Fig. 7992): Up to 250,000 nm (2.2 million in-lb) Spring return (Fig. 7991): Up to 71,000 nm (628,000 in-lb) Working temperatures Standard construction: -20 C to 80 C (-4 F to 176 F) Low temperature version: -50 C to 80 C (-58 F to 176 F) Extreme low temperature version: -60 C to 80 C (-76 F to 176 F) High temperature version: -20 C to 120 C (-4 F to 248 F) Hydraulic manual overrride (HY) Automated valve packages We have engineering and integration professionals in our facilities with extensive knowledge in automation and control as well as applications in all upstream and downstream process industries. They are able to understand the unique need of our clients to create specific automated valve packages that are fit for the purpose. Approvals and standards ISO 9001:2008 quality assurance In accordance with pressure equipment directive (PED) 2014/68/EU, Econ Scotch Yoke actuators are classified as follows: - -150 up to -200 - Category SEP - -250 up to -350 - Category I - -350 up to -600 - Category II - -700 up to -900 - Category III - -1000 up to -1100 - Category IV Classified for use in potentially explosive atmospheres as Group II Category 2, suitable for Zones 1, 2, 21 and 22 in accordance with Annex VIII of Directive 2014/34/EU (ATEX) Safety integrity rating IEC 61508 SIL 2 or SIL 3 in a redundant setup. Passive fire protection Passive fire protection is a key issue in the safety of hydrocarbon process plants. It is considered a reliable method to reduce plant fire risks. For this matter, Econ actuators can be customized to withstand exposure to fire and very high temperatures. A full range of fire proof systems are available, including protective jackets, intumescent coatings and stainless steel enclosure systems. Meets UL 1709 requirements. SIL 2 Capable 5

Threaded parts on the front and the back side of the body for easy assembly of a pneumatic control panel. 6 7 Sintered PTFE metallic bearings protect the sliding and rotating components, suitable for either dry or lubricated working conditions. A PTFE thrust bar prevents yoke pin axial movement, transferring axial loads directly to the drive module case. 4 A vent check valve releases overpressure at the center body while preventing the ingress of gas, corrosive elements and water. 8 A guide block connects the piston rod with the yoke, and compensates for side load deflection thereby reducing wear on rod, bearings and seals.

Valve Automation Centre The ERIKS Flow Control Valve Automation Centre in the Netherlands has a state of the art workshop in which well trained technicians mount pneumatic, hydraulic and electric actuators on valves. Valves and actuators can be modified according to customer specifications and be equipped with options such as valve positioners, limit switches, pilot valves and more. Five pressure test benches allow testing of valves up to DN1200/48. The applicable standards are API 598 and EN 12266 and any other customer specified protocols can additionally be performed. Engineering Working out customer-specific requirements. Product engineering and design. Product development support. Providing 2D and 3D assembly drawings. Supplying 3D CAD models. Workshops Modern workshops of more than 5000 m 2. Facilitating of large and complex projects. Automating and modifying of valves. Mounting, adjusting and modifying according to customer-specific requirements. Logistics More than 2 million products from stock. Automated delivery of products. International presence in 24 countries. Testing Large test facilities. Pressure testing of valves up to DN1200/48. Maximum test pressure 1200 bar. Largest stockist of valves and actuators in Europe.
