Globe valve type AV01 / AV02 / AV03

Product catalog summary

Description: The document describes maintenance-free globe valves (types AV01, AV02, AV03) designed for controlled opening and closing of pipeline systems. They feature an optional regulation plug for flow rate control.

Features: These valves are suitable for both neutral and non-neutral gaseous and liquid media, are maintenance-free, and include a double wall bellows seal as standard. They have a position indicator, non-rising handwheel, and non-rotation lock for each nominal diameter. Installation can be in any position, with the spindle preferably vertical.

Specifications: The valves are available in various sizes (DN15 to DN350) and can operate at temperatures from -10°C to 450°C and pressures up to 40 bar, depending on the design. The body materials vary by type: AV01 uses grey cast iron, AV02 uses SG iron, and AV03 uses cast steel.

Design: The valves are stop valves with a straight-through design, flanges, and bellows seal. The plug design varies between a plug with a marginal seat and a regulation plug.

Materials: Key components include a body, seat ring, bonnet, plug, spindle unit, bellows seal, handwheel, packing ring, hexagon bolt, nut, gasket, and insert nuts. Materials used include stainless steel, pure graphite, and various iron and steel grades.

Dimensions and Pressure Ratings: The document provides detailed dimensions for each valve size and pressure rating (PN16, PN25, PN40). It also includes KVS and Zeta values for flow characteristics and differential pressure requirements for balancing plugs.

Pressure-Temperature Ratings: The document outlines pressure-temperature ratings according to DIN EN 1092-2, with specific values for different materials and temperature ranges.

Article Numbering: The document explains the article numbering system for identifying valve type, plug type, connection, and size.

Additional Information: The document includes information on pressure balancing plugs, installation guidelines, and operational instructions for valves with relief cones.
