INTRODUCTION INTO SYPRIS AUTOMATED SELF-OPENING CLOSURES-MANWAYS
ASME Self-Opening Opening Pipeline Closures, Process Piping Closures, ASME Pressure Vessel Closures
Tube Turns Automated Closures have the flexibility of design and can be developed and manufactured to meet your needs. Our Automated Closures are located in industries throughout the world. Applications for Tube Turns Automated Closures include Pipeline Launchers and Receivers and operations with batch processes such as pulp and paper mills, food process, chemical plants, and petrochemical plants.
Electric Operated Automated Closures are supplied with electric motors and appropriate gearboxes to drive the yoke bolts and to open and close the head. Electric circuits are wired to a central junction box and a push-button control panel is included. A wiring diagram is provided for onsite wiring between the junction box and the control panel to complete the installation.
Pneumatic Operated Automated Closures are supplied with air-driven motors, a gearbox to drive the yoke bolts through a joint chain drive, and a gearbox to open and close the head. Shop air from 60 psi to 90 psi is used for the operation of the unit through a control panel provided with lever-actuated control valves.
Hydraulic Operated Automated Closures are similar to those described above except that hydraulic motors are used for the driving force. A hydraulic pump system with electric controls can be provided with the units or by the end-user.
The flexibility of our Double Bolt Closure design and can be developed and manufactured to meet your needs.
Stainless Steel, Exotic Coatings, Weld Neck Flanges, and Lifting Eye Bolts are just some of the options that can be added to meet your application.
Closure Safety Locking Device
An additional feature that can be added to the Yoke Style Closure is the Safety Locking Device. This device is intended to prevent the opening of the closure under pressure. It consists of a cylinder/piston connected to the interior of the closure and a latch plate. Whenever there is pressure inside the closure the piston is extended and engages the latch plate. This prevents opening of the closure under pressure. When the pressure has been reduced, the piston retracts, allowing the closure to be opened. This is a closed system and does not release it’s contents to the atmosphere.
Automation provides a tight seal that prevents leakage and exposure of the operators to fumes and the medium which is potentially hazardous to their health. To prevent inadvertent opening of these closures, they are normally furnished with the following safety systems:
A. Electrically Operated Closures are equipped with a pressure switch and an electrical relay.
B. Pneumatically Operated Closures are equipped with a pressure switch and a solenoid valve.
C. Hydraulically Operated Closures are equipped with a pressure switch and an electrical relay

Less Time Needed To Open Closure For Time Critical Applications
A. It is fast! Depending upon size, the opening and closing cycle can take less than one minute.
B. One man can open it. He does so by merely pushing a button. As a result of these savings in operating costs, an early payback in your initial investment can be realized.
Simple Maintenance
Since the operation is simple, direct, and positive, Automated Closures require little or no maintenance other than replacement of the O-ring and periodic inspection of yoke bolts and nuts for wear. The human element is virtually eliminated in that the automation mechanism of the closure performs all the work.
Variety of Applications
Applications for TUBE TURNS? Automated Closures include Pipeline Launchers and Receivers and operations with batch processes such as pulp and paper mills, food processing, chemical plants, and petrochemical plants.
ASME Stamped Closures
Code stamping of Tube Turns Hinged Closures is available on request at a nominal extra cost. This includes (1) the furnishing of a Partial Data Sheet verifying shop inspection of the unit by a commissioned inspector of the National Board of Boiler and Pressure Vessel Inspectors, and (2) the affixing of the ASME stamp.
