The Morin Partial Stroke Test Device (PSTD) was developed to allow users to test emergency shut-down valves without disrupting the process. The PSTD unit is locked out when the unit is in service and the valve functions normally. When the unit needs to be tested, the operator unlocks the device and inserts the stop pin, allowing for 15 degrees of valve travel to sufficiently test the valve package. Unlike electronic versions, you are guaranteed a hard stop and no over-travel, time after time, without any special calibration.

What makes SOMAS actuators so special? One reason is that they have been specially designed to cope with the requirements of the process industry for reliable operation and precise control. Our actuators are mainly intended for use with SOMAS valves , but they can be easily adapted for use with other valves demanding a 90 degree arc of operation.
We have spared no effort in order to eliminate any backlash between the moving parts of the actuator or between the actuator and the valve. This has created the neccessary prerequisites for pinpoint precision and has laid the foundation for accurate diagnostics.

Standard EA Series Rotary Actuators
The standard EA series of actuators contains both gear driven crankshaft and hydraulic powered axial shaft actuators. They can be used with combustion air dampers and a wide variety of low, medium and high torque rotary shaft valve bodies with crankarms. The EA series can accommodate applications requiring position to be held or returned to normal position during power interruptions. Used for two-position floating and proportional electric control, these actuators are employed wherever it is desirable to move a load in either direction or to stop it at any point in the stroke. Typical applications include heat treat furnaces, ovens, heat recovery systems, and water and oil cooling systems. Eight base models plus variants are included in the complete product range, offering a variety of control action, motor voltage and frequency, torque, return action and optional features.
Features
- proportional actuators with builtin feedback potentiometer
- spring return and non-spring return
- 24Vac, 120Vac and 240Vac
- oil immersed gear train
- SPDT auxiliary switch
- compatible with VB series valves

Positioner - Series 5000
Electro/pneumatic or Pneumatic
The Posi-flate Series 5000 Positioner provides accurate valve positioning with advanced features. It may be used with 3-15 PSI pneumatic control signals (as shown), or fitted with one of three current-to-pressure transducers for 4-20 mA signal inputs. The pneumatic positioner is available with many options including limit switches, position feedback transmitter and a visual dome indicator.
Applications
A high spool valve, plus an adjustable gain system, make the pneumatic positioner well suited for use with all pneumatic rotary actuator types including rack-and-pinion, heavy duty and others.
The positioner housing is constructed from durable die-cast aluminum and treated with a dichromate undercoat and polyester powder top coat for protection against the toughest applications in all process industries.

The Becker Model VRP Double-Acting Pilot provides pressure control when utilized with a double-acting piston actuated control valve. The Model VRP Valve Regulator Pilot is the “original” VRP-Pilot and is often referred to as the “VRP Classic.” The VRP measures process sensing pressure and positions the double-acting actuator to maintain the setpoint. The VRP Pilot may be utilized for pressure control applications with setpoints ranging from 1.0 psig (6.9 kPa) to 1300 psig (8964 kPa). The VRP is typically utilized when Bleed to Pressure System (BPS™) may be used to completely eliminate atmospheric bleed emissions. The VRP Classic maintains the simplicity of the original VRP concept with “standard” setpoint accuracy and performance. For higher level of performance and accuracy, the Model VRP-CH Valve Regulator Pilot should be utilized. The VRP Classic is utilized primarily by long-term customers that have a large installed base of the original VRP Pilots.

Good reasons for this automation:
No radial forces have an effect on the shaft of the fitting.
This saves as well as the bearing and the packet
With the hollow shaft design or an adapter hub the required
Eckart rotary actuator can adapted to every Zwick high performance flap
Very fast control times (e.g. 90° in 0.2 seconds) can be realized
By the optimal end cushioning of the Eckart rotary actuator the
closing stop position of the fitting is also saved
The regulation of the volume flows is very simple and repeating exact
No additional lubrication is necessary
