ProControl GMBH factory in Landau-Pfalz, Germany ProControl srl Headquarter in Italy

Most valve actuators are generally required for on / off applications. The single greatest cause of actuator operational failure is corrosion and deterioration of operating parts. ProControl actuators have been engineered with these problems in mind and the basis of our design is in order to ensure long term product reliability. ProControl carries out every element of design, assembly and material selection, and all of the latest industry requirements and regulations have been implemented in our current design. Our technical department works with the latest cad design software. Quality...

ProControl actuators all share a common construction philosophy known as modularity, which is achieved by utilizing a consistent engineering design throughout our complete range. Power cylinders, spring containers, manual overrides, control systems and other features can be assembled in various different positions thus allowing to cover all requests in terms of fail position and additional features. With large stock of finished and semi-finished components always available, actuators can be assembled and supplied with very fast deliveries.

Scotch Yoke Mechanism CANTED YOKE SYMMETRIC YOKE CANTED AND SYMMETRIC SCOTCH YOKE MECHANISM The scotch yoke mechanism is precisely positioned inside a perfectly sealed housing which protects it against corrosion in the most adverse environments. The housing also encompasses a stem thrust support device suitable to withstand the transversal forces generated during rotation and to ensure the proper alignment of the piston rod with the sliding blocks. Low rotational friction is also ensured by means of oversized precise fitted bronze yoke shaft bushings which contribute to extend heavy duty...

Cylinders & Springs PNEUMATIC / HYDRAULIC CYLINDERS & SPRING CONTAINERS The cylinder tubes are machined, polished to mirror finish and electro less nickel plated internally in order to reduce surface roughness to the lowest value and to provide highest protection against corrosion and low maintenance. For pneumatic actuators the sealing with flanges and piston is performed by means of a floating O-ring design and guided internally by a sliding ring in Teflon graphite. For hydraulic actuators the sealing with flanges and piston is performed by means of O-rings and guided internally by a...

QUARTER TURN COMPACT PNEUMATIC ACTUATORS SINGLE & DOUBLE ACTING SPS-K & SPD-K series DESCRIPTION ProControl has created the SPS-K & SPD-K series actuators based on the markets requirements for a new compact heavy duty high performance design actuator. For single acting models the cylinder assembly also contains the spring, thus the advantage of a compact design.

KEY FEATURES • Fabricated entirely from low temperature carbon steel according to ASTM A352 gr. LCB and ASTM A350 LF2 • Totally enclosed weatherproof housing • Scotch yoke mechanism to suit valve torque requirements • Relief vent to expel undesired overpressure • Low pressure pneumatic cylinder for supply pressures up to 12 bar design suitable for instrument air or sweet / inert gas applications or special application with material according to NACE requirements for sour gas supply medium • Carbon steel piston with dynamic floating O-ring seals coupled with lubricating piston guide rings •...

QUARTER TURN PNEUMATIC ACTUATORS SINGLE & DOUBLE ACTING SPS & SPD series DESCRIPTION The SPS & SPD series, heavy duty high performance design actuators, are for ProControl the long-standing products of the range. The reliability and firmness that distinguish them arise from a constant innovation research combined with the experience gained over the years.
