Product catalog summary

Technical Specifications
The KGU Urethane Knife Gate Valves are constructed with a cast iron body lined with urethane, ideal for handling abrasive slurries and dry materials. Key features include a stainless steel gate, long-life packing, and a corrosion-resistant yoke sleeve.

Materials of Construction
- Body: Cast iron ASTM A 126, Class B
- Packing: PTPE impregnated synthetic fiber
- Packing Gland: Stainless steel or ductile iron depending on size
- Seat Material: Urethane
- Yoke Sleeve: Aluminum bronze or ductile iron
- Yoke: Carbon steel

Valve Selection and Shutoff Capabilities
Urethane seats provide leak-tight performance. Pressure ratings vary by size: 4-12 inches at 150 psi, and 14-24 inches at 50-75 psi.

Flow Characteristics
Flow coefficients (Cv and Kv) are specified for each valve size, indicating flow capacity. The K factor and area of opening are provided for calculating equivalent pipe length.

Applicable Standards
The valves meet standards such as ANSI B16.1, ANSI B16.5, and international standards like JIS, DIN, ISO, and BS.

Valve Weights
Weights are listed for each valve size, with additional weights for cylinder actuators.

Ordering Information
Instructions include codes for valve size, style, end connection, gate material, and packing material, with examples for clarity.

Actuators
Options include manual, lever, handwheel, bevel gear, cylinder, and electric motor actuators, each with specific ordering codes and pressure differential limits.

Accessories
Available accessories include positioners, air filter regulators, manual loading stations, filters/strainers, and control valves, with ordering examples provided.

Dimensions
Dimensions for flanged ends and bevel gear actuators are specified for each valve size. Note that dimensions may change, and certified drawings are available upon request.

KGU URETHANE KNIFE GATE VALVES TECHNICAL SPECIFICATIONS > Lever actuators can be furnished on 4 (100 mm) valves for applications where rapid valve operation is required or where space prevents use of a standard handwheel or bevel gear actuator. Maximum pressure differential required for valves with lever actuators should not exceed the limit listed. Maximum is based on the operating force for the valve size. To order, add the lever actuator code to the basic valve order code. > Valve SizeOrder CodeMax. Pressure Differentialpsi/kPa 4Ԕ100 mmMN-LV75520 Order Example: KGU, 4, W1, S2, C*MN-LV > All...

KGU URETHANE KNIFE GATE VALVES TECHNICAL SPECIFICATIONS > Bevel gear actuators provide vertical mounting of the handwheel or chainwheel, or can be used where space limitations prohibit the use of standard handwheel. A mechanical advantage makes large valve operation easier and faster. > Bevel gears on 4-12 (100-300 mm) can be mounted at standard 90, 180, 270 degree mounting. Specify as second line information. On valve sizes 14-24Ԕ (350-600 mm), use the appropriate order code from the chart for standard or 180 mounting, or 90 or 270 mounting. Specify which position as second line information....
