General Information and Specifications

Mounting Hardware

• Order processing cannot begin until all relevant information and drawings, if required, are obtained by Sebewaing Tool & Engineering Company from our customer, the manufacturer or the end user.

• Bracketry may be tubing or formed based on the application.  Sebewaing Tool & Engineering Company reserves the right to use methods developed by our engineering department unless otherwise specified by our customer.

• ISO and NAMUR mounting provisions may allow for direct drive of some components, omitting the need for a drive coupling.  A price reduction may result.

• Actuators are mounted parallel to the flow in a "fail closed" position.  This is the standard mounting orientation for Sebewaing Tool & Engineering Company.  The purchase order or request for quote must specify if there is to be any deviation from this standard.  Perpendicular mountings of "fail open" assemblies may increase mounting hardware price.

• Kits are supplied for on/off service.  Inquire with factory for control/modulating service.  Couplings with enclosed pockets available upon request.  

• Standard carbon steel linkages consist of an enamel painted bracket and coupling with all required Grade 5 zinc plated fasteners.  Epoxy coating is also available.  Stainless steel kits consist of a 304SS bracket, 303SS coupling and all required 18-8SS fasteners.  Hex head cap screws are typically supplied.  However, Sebewaing Tool & Engineering Company reserves the right to supply fastener style based on design criteria.

• Additional charges may apply for materials other than those noted.

• Additional charges required for: stud mountings, packing gland adaptations, cradle brackets, jacketed valves, sleeved couplings, two piece split couplings and couplings with set screws, heavy duty brackets (3/8" wall and above) and special bracket height requests.

• Quantity discounts are based on quantities of the same kit.

• Project pricing available.  Please note: any add-ons to a project purchase order, after the hardware has entered production, will be reviewed and may be repriced based on the quantity.

• For applications involving torque values above 17,000 in. lbs, consult factory for heavy duty kit pricing.

• Blanket order pricing is available.  Inquire with your particular requirement.

• All purchase orders will be confirmed via return fax, e-mail or phone call.

• Stock items can ship 1-2 working days after receipt of order;  ship date to be determined at the time of order.

Engineering Design

• Bracket material thickness - varies with the specific process requirements.  Below are commonly used material thicknesses for various valve types and sizes.

• Bolt clearance holes are 1/16" (.06") larger than the nominal bolt diameter.

• Formed brackets have a height tolerance of +.03"/ -.02" . Height tolerance for tubing brackets is standard tube stock tolerance.

• Mounting hole pattern tolerances are held to +/- .015".

• Coupling drive tolerance is +.002"/.005" above the published valve stem dimension.

• Coupling length tolerance is +.005"/-.02".

Materials 

• The thickness of the material used for mounting brackets is determined by the size of the valve, actuator and torque requirements.  1/8" to 3/8" thick material is used for formed brackets. Applications requiring thicker material will either be fabricated or supplied as tubing.  

• Tensile strength for carbon steel brackets is 58/80,000 psi.

• Stainless steel material for standard brackets is 304-SS with a tensile strength of 100,000 psi.  316-SS material is also available.

• Carbon steel material for standard couplings are made from 1018 C with a tensile strength of 85,000 psi. 1020, 11L17 and 12L14 material may also be used.

• Stainless steel couplings are made from 303-SS stock with a tensile strength of 85/120,000 psi. 17-4 SS and 316-SS are also available.

• Carbon Steel kits are supplied with Grade 5, zinc coated, North American fasteners.

• Stainless steel kits are supplied with 18-8 SS fasteners or 316-SS fasteners, if required.  Bronze, hastelloy and aluminum fasteners are also available.

Manufacturing

• Hardware may be uniquely designed to your own specific engineering requirements.

• Standard finish is one coat of primer and one coat of Industrial Maintenance Coating, Tile Clad II Enamel, Part A, a HIPAC Coating.  Finish 90 +- 0 units @ 60 degrees. The drying schedule @ 77 degrees and 50% RH @ 9 mills wet: To touch - 1 hour; tack free - 4 hours; to recoat - 6 hours.  Other finishes, including epoxy, zinc plating or endurion, are available upon request.
