Technical Catalog Overview

This document is a technical catalog detailing diaphragm valves, specifically membrane valves. It provides comprehensive specifications, design features, operational guidelines, and dimensional data for various valve types and sizes.

1. Valve Description and Functionality

• The diaphragm valve features a low-maintenance membrane actuator controlled by air or electric actuators.
• Valve types include normally closed (NC), normally open (NO), and double acting (DA) control functions.
• Medium wetted parts and actuator housings are made from high-grade plastic materials suitable for specific applications.
• Membrane valves are designed for precise control of fluid or gas flow, with options for pneumatic or electric actuation.

2. Technical Features

• Valve chemical resistance depends on the type of fluid, temperature, pressure, and valve materials.
• Valve design includes optimized flow paths to reduce pressure drops and improve system efficiency.
• Perforated circular discs eliminate corrosion risks on the valve body.
• Stainless steel mounting inserts support the valve and ensure durability.
• Standard handwheels and actuator options (pneumatic, electric, manual) are available for valve operation.
• Valve actuators support medium pressure ranges and are compatible with various control signals.
• Standard handwheel and actuator mounting comply with industry standards for easy integration.

3. Materials and Construction

• Valve bodies and wetted parts are constructed from high-quality plastics and metals to ensure chemical resistance and mechanical strength.
• Membranes are made from elastomeric materials selected based on chemical compatibility and application requirements.
• Actuator housings are designed for durability and environmental protection.

4. Dimensional Data and Specifications

The catalog includes detailed dimensional tables for various valve sizes (DN 15 to DN 50), listing parameters such as:

• Dimensions: d, L, G, H, J, K, S, L1, Z, B, Q, H1, H2, H3, A, B, C
• Pressure ratings (PN)
• Weight in grams

These dimensions support valve selection and installation planning.

5. Flow Characteristics

• Flow rate coefficients (Cv) and flow efficiency data are provided to assist in hydraulic calculations.
• Graphs and charts illustrate flow rates versus pressure drops for different valve sizes.

6. Standards and Compliance

• The valves comply with relevant industry standards for design, materials, and performance.
• All descriptions and illustrations are for guidance only and do not constitute a contractual obligation.
• Dimensions are nominal and subject to change without prior notice.

7. Usage and Maintenance Recommendations

• Users must verify chemical compatibility and operating conditions before installation.
• Proper actuator selection (pneumatic, electric, manual) is critical for valve performance.
• Regular maintenance is recommended to ensure valve longevity and reliability.
• Valve operation should follow manufacturer guidelines to avoid damage or malfunction.

8. Contact and Support

Contact information for the manufacturer or supplier is provided for technical support and ordering.

Summary

This technical catalog provides detailed information on diaphragm membrane valves, including design features, materials, dimensions, flow characteristics, and operational guidelines. It serves as a comprehensive reference for engineers and technicians involved in valve selection, installation, and maintenance in fluid control systems.
