Selecting check valves

Product catalog summary

Overview: This document provides comprehensive details on PVC-U and PVC-C valves, including their specifications, installation procedures, and material properties. It covers various valve types such as ball, check, and butterfly valves, focusing on their applications, materials, and operational guidelines.

Specifications: The document details specifications for different valve series, including dimensions, pressure ratings, and material compositions. Valves are available in sizes from D16 to D110 (⅜” to 4”) and are made from PVC-U and PVC-C materials, designed to resist many inorganic chemicals, and available in both metric and imperial standards.

Valve Types and Features:

Ball Valves: Available in Standard, Industrial, PN 10, Compact, and 3-way series, featuring easy installation and maintenance, with options for vertical or horizontal use.
Check Valves: Include Spring Series, Ball Series, and Swing Check types, designed for reliable closure and minimal pressure loss, suitable for various liquid types.
Butterfly Valves: Offered in Industrial, Standard, and Classic series, used for high flow applications and are space-efficient.
Actuated and Hydraulic Valves: Include motorized and hydraulic options for automated control in various systems.

Installation and Maintenance: Valves are factory-tested for quality assurance and can be installed both vertically and horizontally. They are designed for easy maintenance and are compatible with different piping systems.

Materials and Components: Valves are constructed with components such as stainless steel springs, EPDM or Viton® O-rings, and PVC-U/PVC-C bodies, ensuring durability and chemical resistance.

Applications: Suitable for transporting clean, non-viscous liquids without particles, used in various industrial applications, including water flow systems, where reliable closure and minimal pressure loss are critical.

Performance Data: Includes performance charts showing pressure loss and flow rates, as well as temperature and pressure ratings for different valve sizes and materials.

Technical Specifications: Working pressure for PVC-U and PVC-C valves at 20°C (73°F) is PN 16 (240 psi) for sizes D16 to D63 (⅜” to 2”) and PN 10 (150 psi) for sizes D75 to D110 (2½” to 4”).

Pressure Loss and Temperature Graphs: Diagrams illustrate pressure loss and pressure/temperature relationships for various valve sizes, aiding in understanding flow characteristics and pressure requirements.

Assembly Instructions: Instructions for assembling solvent socket or threaded unions emphasize using PVC-U or PVC-C adhesive and Teflon® tape for threaded unions, with a recommended drying period of at least 1 hour per bar of working pressure before applying pressure.

Valve Features: Valves are factory tested, easy to install and maintain, usable both vertically and horizontally, resistant to many inorganic chemicals, and have excellent flow characteristics. Available sizes range from D16 to D110 (⅜” to 4”), with standards including Metric, ASTM, and British Standard. Threaded versions are available in BSP and NPT, with O-Rings in EPDM or Viton®.

Material and Parts: Lists materials used for various valve components, such as PVC-U/PVC-C for the body and cone, stainless steel for the spring, and EPDM/Viton® for O-Rings, with detailed part descriptions and dimensions for different valve sizes.

Installation Recommendations: Requires little space in piping systems, install with pipe and flange DIN PN 10, and do not install the valve at a distance lower than 5 x D from the pump outlet.

Components: Body, ball, union nut, end connector, closing ring, seal-carrier, and foot valve screen made of PVC-U, with O-rings available in EPDM or Viton®.

Additional Information: Check valves “Y” Ball Series designed for vertical ascending and horizontal operation, swing check valves available with EPDM or Viton® O-Rings, and accessories and mounting kits available for specific valve types.

PVC-U & PVC-C VALVES Concept & typical application Concept et applications typiques Concepto y aplicaciones Conceito e aplicações Shuts off flow by means of a cone pushed by a spring which helps it to obtain an entirely watertight closure. The difference in pressure between two points of the installation is able to overcome the resistance of the spring, thus making the fluid flow in the desired direction and preventing the flow passage in the other.
