Bi-Directional Knife Gate Valve Techincal

Product catalog summary
Materials of Construction: The DeZURIK KBD Knife Gate Valves are made from various grades of stainless steel (304, 316, 317) according to ASTM standards. The packing materials are PTFE impregnated synthetic fibers, and the gate matches the body material. The seat ring and retainer seat are 316 stainless steel with resilient materials like chloroprene and fluoro rubber.
Applicable Standards: The valves comply with TAPPI TIS 405-8 for pulp and paper mills, MSS SP-81 for stainless steel knife gate valves, and ANSI B16.5 for carbon steel flanges.
Valve Selection: Selection involves specifying valve style (KBD), size (3" to 12"), body material (304, 316, 317 stainless steel), end style, body style, packing material, and resilient seat material. The pressure rating is 150 psi for sizes 3" to 12".
Ordering: Complete the valve order code with necessary specifications. An example is provided for clarity.
Rotary Manual Actuators: Valves can have handwheels, chainwheels, and bevel gear actuators, sized based on valve size and pressure differential, with specific ordering codes.
Manual Actuator Accessories: Include chain types, locking devices, handwheel extensions, and position indicating floorstands. Minimum installation dimensions are specified.
On-Off Cylinder Actuators: Available with pneumatic or hydraulic cylinders for on-off positioning, with supply pressures of 50 or 80 psi. Actuator sizing is provided for different media and pressure conditions.
Electric Motor Actuators: Typically involve electric motors for valve operation, though not detailed in the text.
Dimensions and Weights: Detailed dimensions and weights for valves and actuators are provided, including Cv/Kv values and K factors for flow calculations.
Overview: The document provides technical specifications and ordering information for DeZURIK Cylinder Actuators and Bi-Directional Knife Gate Valves, including accessories, positioners, air filter regulators, manual control panels, and valve dimensions.
Positioners: DeZURIK Cylinder Actuators can have pneumatic or electronic positioners for throttling control, enclosed and mounted on the superstructure. Refer to specific bulletins for ordering information.
Air Filter Regulator: Provides clean, accurate air pressure to actuators and positioners. Ordering information is in bulletin 83.00-2.
Manual Loading Station Control Panel: Suitable for all positioning pneumatic actuators with an output of 0-15 psi. Includes a signal output gauge and pressure reducing valve. Order using code ACC*CNP025.
Four-Way Manual Control Valves: For pneumatic or hydraulic double-acting cylinder actuators, can be ordered mounted or separately. Use specific codes for ordering.
Position Indicating Switches: Available for double-acting cylinder actuators, indicating full open and closed positions. Order as part of a complete assembly using appropriate codes.
Speed Control Valves: Control the speed of valve opening or closing with pneumatic actuators. The operation speed is adjustable.
Four-Way Solenoid Valves: Can be ordered mounted and piped as part of a complete assembly or separately. Refer to DeZURIK bulletin 84.00-1 for details.
Electric Motor Actuators: Knife Gate Valves can have electric motor actuators from various manufacturers. Specify valve order code, shutoff pressure, service conditions, and other specifications when ordering.
Valve Dimensions: Detailed dimensions for various valve sizes are provided, including handwheel, chainwheel, and cylinder dimensions.
Notes: SPX Process Equipment is ISO 9001 certified. The document includes contact information for sales and service and notes that design features and materials are subject to change.
