Check Valve by Disc - Technical Specifications and Dimensions

General Description

This document provides technical specifications and dimensional data for a check valve with a disc, suitable for both horizontal and vertical assembly. The valve conforms to DIN standards, specifically PN-16.

Dimensional Data Table

The table lists nominal diameters (DN) alongside corresponding key dimensions (A, B, C, D, E) and the number of bolt holes (N). Dimensions are given in millimeters.

• DN sizes range from 40 to 200.
• Dimension A varies from 180 mm (DN 40) up to 500 mm (DN 200).
• Dimension B ranges from 150 mm to 340 mm.
• Dimension C ranges from 110 mm to 295 mm.
• Dimension D is consistently 18-24 mm depending on size.
• Dimension E is 18-23 mm.
• Number of holes (N) varies from 4 to 12 depending on DN.

Materials and Components

The valve components and their materials are specified as follows:

• Body: Stainless Steel CF8M
• Disc (Closure): Stainless Steel CF8M
• Nut: Stainless Steel 316
• Arm (Rod): Stainless Steel CF8M
• Hinge (Axis): Stainless Steel CF8M
• Cover: Stainless Steel CF8M

Other materials and dimensions are available upon request.

Key Notes

• The valve is designed for PN-16 pressure rating according to DIN standards.
• Suitable for installation in both horizontal and vertical orientations.
• The number of bolt holes and dimensions scale with nominal diameter to ensure proper fitting and sealing.
