Data sheet SD24

Product catalog summary

Specifications:
The document details the specifications of the SD24 pressure reducer made by END-Armaturen GmbH & Co. KG. It is constructed from bronze with a fully relieved single-seat valve and an integrated strainer. The connection is via flanges ranging from DN20 to DN80, compliant with DIN EN 1092-3 standards. The pressure setting is adjustable through the rotation of an adjustment stem, with a pressure gauge connection available on both sides (G ¼"). The inlet pressure is 16 bar, extendable to 25 bar upon request, while the outlet pressure ranges from 1 to 8 bar, with a DVGW version available up to 6 bar. The temperature range is up to 95°C, suitable for water, neutral non-adhesive liquids, compressed air, and neutral non-combustible gases. The materials used include bronze for the body and spring bonnet, stainless steel for medium-contact parts, EPDM for seals, and steel for the spring. Optional features include a pressure gauge and DVGW approval.

Ordering Information:
The ordering code is structured as follows: the first two digits represent the product (SD for pressure reducer), the next two digits indicate the material (24 for bronze/EPDM), the fifth digit denotes the pressure range (00 for PN16), and the last three digits specify the connection size (e.g., 03 for DN20).

Dimensions and Flow Rates:
The document provides a table of dimensions and flow rates for various DN sizes, from DN20 to DN80, with corresponding pressure ranges, dimensions, Kvs values, and weights. A flow rate diagram illustrates the relationship between pressure drop and flow rate for different DN sizes.

Flow Rate Determination:
For liquids, the necessary diameter (DN) can be determined using a diagram based on the desired flow rate (m³/h). According to DVGW guidelines (DIN 1988), a flow speed of 2m/s should not be exceeded in domestic water supply systems. For compressed air and other gaseous media, the typical flow speed is 10-20m/s. Flow rates for gaseous media should be stated in industrial m³/h, and if given in normal cubic meters, they should be converted to industrial cubic meters before using the diagram. Industrial cubic meters are based on the pressure condition of the medium behind the pressure reducer.

Leistungsbestimmung von Druckminderern / Determination of size and capacity of pressure reducers (gaseous medium, liquids) Für Flüssigkeiten: Mit Hilfe des Diagramms lässt sich zu einer verlangten Durchussmenge V (m³/h) die erforderliche Nennweite (DN) bestimmen. In Hauswasserversorgungsanlagen soll nach DVGW- Richtlinien (DIN 1988) eine Durchussgeschwindigkeit von 2m/s nicht überschritten werden. Für Pressluft und andere gasförmige Medien: Die übliche Durchussgeschwindigkeit für Pressluft liegt bei 10…20m/s. Für gasförmige Medien ist die Durchussmenge V immer in Betriebskubikmeter...
