FLANGED BALL VALVES

Body Parts are of investment casting, normalized for added strength, and marked with a HET number for full traceability. Carbon Steel bodies are phosphate coated for increased corrosion resistance.

The Ball, Seat, and Stem are precision machined for bubble-tight shut-off and less operating torque. Balls are of mirror finished. Seats feature relief slots to relieve pressure, and stems are heavy-duty blowout-proof, with double "D" connections to the ball and operator mounting.

The Stem Seal automatically adjusts and acts as a secondary seal between the stem and body.

Stem Packing An adjustable V-ring design creates multiple seals between the stem and body.

Secure Mount Flanged Series Valve offers ease of automation due to a dedicated ISO pad that complies with 5211 and is integral with the body.

Locking Devices feature a locking arrangement through a padlock to secure the handle in position to prevent accidental movement of the ball.

UNI - DIRECTIONAL KNIFE GATE VALVES

Body : Cast monoblock with raised face Reinforced ribs in larger diameters for extra body strength. Internal gate wedges and guides ensure tighter shut-off. full-port design for greater flow capacity and minimal pressure drop. Internal design avoids the buildup of solids that would prevent the valve from closing.

Gate :The gate has a precision grinding finish on both sides to prevent packing and seat damage. The bevelled knife-like gate edge with machined teeth on each side pushes away or cuts through solids in the flow stream on request. The thickness and/or material of the gate can be changed for a higher pressure requirement.

Seat : Both metal and resilient seated valves are offered in a 100% round port design. This is a unique design that fixes the seat in the internal of the valve body with a stainless steel retainer ring.

Resilient : Standard EPDM is also available in different materials such as CR, NBR, Viton, PTFE, etc.

Packing : Long-life packing with several layers of Self-Adjusting PTFE-impregnated braided packing at 400°F (205°C), PTFE-impregnated braided packing at 500°F (260°C), and other packing options are available on request.

Stem : The standard stainless steel stem offers a long, corrosion-resistant life. For rising stems, a protector tube is provided to ensure there is always enough space for the gate to open and protect the stem thread Bellows.

Actuators: Hand wheels, Chain wheels, Levers, Bevel Gears, Pneumatic Cylinders, Hydraulic cylinders, and Electric motors.

CHECK VALVE

Check valve models are primarily single-plate swing check valves with a short pattern body conforming to the API 6D and ASI B16.10 face-to-face dimensions.

Design Standard: These valves adhere to the standards outlined in API 6D and ASI B16.10 regarding face-to-face dimensions.

Construction & Reliability: The valve features a simple yet robust construction that ensures reliable operation.

Disc Design & Operation: The innovative low inertia disc design of the valve allows for its opening and closing with minimal differential pressures.

Pressure Drop & Applications: These check valves exhibit a low pressure drop when fully open, making them particularly suitable for pump discharge applications.

Shut-Off Mechanism: The combined design of the eccentric disc shaft and the disc seat ensures a positive shut-off, effectively blocking the return of the media.

Installation Benefits: The short face-to-face dimensions and light weight of these check valves facilitate a straightforward, space-saving installation between the companion flanges.

KEY FEATURES

1. Space-Efficiency: Due to their low face-to-face dimensions, these valves require less mounting space compared to conventional valves.

2. Lightweight: The total weight of the Series 40 check valves is 16-17% less than conventional valves, making them easier to handle and transport.

3. Short Wafer Body: The short wafer body design allows for mounting with shorter fasteners, an advantage over standard flanged swing check valves.

4. Easy to Handle & Maintain: These valves are designed to be easily handled, packed, transported, installed, and maintained, thanks to their user-friendly design and construction.

5. Simplified Maintenance: The Series 40 check valves offer trouble-free maintenance due to their simple design and a fewer number of parts involved.

6. Ease of Installation: The controlled outside diameter of these valves enables self-centering in pipelines, which simplifies the installation process.

APPLICATIONS

The Stauffer series of 40 wafer-type check valves are extremely adaptable and have numerous application possibilities, including:

Water treatment plant and waste effluent plant

Balance of plants and cooling water plants

 Chemical industry and sugar industry

 HVAC plants and power plants

 Oil and gas plants

 Paper industry

 Desalination plants and metallurgy plants
