WHY USE ALSA HDPE CHECK VALVES, SCREENS & OTHER PRODUCTS
- High-Density Polyethylene (HDPE) is a versatile plastic material that finds applications in various water conduction fields, including Agriculture, Mining, Water Works, and Industrial Operations.
Let’s explore how HDPE stands out and its benefits:
- What Is HDPE?
- High-density polyethylene (HDPE) is a type of polymer known for its high strength-to-density ratio.
- Advantages of HDPE:
- Strength and Durability: HDPE plastic offers exceptional strength, rigidity, and durability.
- Heat, Moisture, and Mold Resistance: HDPE is resistant to environmental conditions, making it suitable for outdoor use.
- Environmentally Friendly: Both components SS Mechanism and Plastic Body are Recyclable, contributing to sustainability.
- Weather Resistance: HDPE doesn’t warp, shrink, or decay due to weather exposure.
- Bug Resistance: HDPE is not susceptible to termites or other pests.
- Fire Resistance: HDPE doesn’t pose a fire hazard.
- Additional Notes regarding ALSA HDPE CHECK VALVES:
- ALSA HDPE Check Valves and Screens can be used together as foot valves. We are based in Miami, Florida.
- ALSA normally stocks in Miami HDPE CHECK VALVES and SCREENS from 3" up to 12", other sizes up on request.
- ALSA HDPE FLAPPER FOR THE CHECK VALVES stocks with standard RUBBER. Viton Seals upon request.
- ALSA HDPE CHECK VALVES works normally and effectively regardless of the installed position: Horizontal, Vertical, or inclined.
- Easy Inspection and Maintenance due to simple design.
- The Comprehensive design of the Valve body allows a flow without restrictions.
- The closing contact of the disc is performed by HDPE and Rubber, eliminating wear and tear.
- The flap cannot jam in the open position. All the working mechanism is made of SS.
- The closing mechanism is designed to close a moment before the flow is reversed. This decreases the loud hammering sound of water hammer.
- The design allows a small force in the springs on the articulated mechanism in the valve closed position, manages to keep a closure pressure much greater than that would be in the case of the springs attach directly on the flapper.
- Flap closing by spring action. A prominent feature of Poly Check valves is the action applied by two springs that Act on an articulated mechanism attached to the closing disc.
- Flap opens with low pressure around 5 psi.
- Mechanism, nuts and bolts in SS 316L.
GENERAL CHARACTERISTICS OF THE HDPE CHECK VALVES
1. Mechanism, nuts and bolts in SS 316L.
2. Closing inner disc made in HDPE with RUBBER sealing ring (VITON up on request).
3. Large body built in HDPE that allows flow without restrictions.
4. The closing mechanism has been designed to remain open until the instant flow is inverted, avoiding the hammer effect and not getting blocked in the open position.
5. Flanges are based on DIN PN 10 standard norms and ANSI C-150 (US STOCK).
6. Working Max. Pressure: 150 psi
7. Minimum Working Pressure (Disc Opening): 5 psi.
Sizes from 3” up to 40” Check Valves and Screens
Sizes 3” to 12” usually available in our Stock.
Larger sizes available up on Request and Pre-Pay.
No Refunds or Order Cancellations.
