DIN Flanged Ball Valve Short Type Stainless Steel

Key Features

• Compact Installation Profile: The short body helps accommodate isolation points within machinery, modular systems and confined equipment layouts. Installation planning can focus on the complete assembly, including handle movement, actuator dimensions and maintenance access.
• One-Piece Construction: A single main housing contains the internal components. Servicing should follow the confirmed retainer and seat-removal procedure after isolation and depressurization.
• Full-Bore Passage: The ball opening aligns with the pipeline when fully open, reducing obstruction and helping limit pressure loss through equipment connections.
• Quarter-Turn Operation: A 90-degree rotation changes the valve between open and closed positions, providing convenient local control.
• Actuator Interface: An ISO 5211 top mounting flange supports automation. Actuator selection should account for valve torque, maximum differential pressure and operating frequency.
• Anti-Static Component: The published construction includes a stainless steel anti-static device. Confirm any electrical-continuity testing required by the intended service.

Materials and Construction

• Body: CF8, CF8M or CF3M stainless steel, according to the ordered configuration.
• Ball, Stem and Retainer: Stainless steel.
• Ball Seats: RTFE, as listed in the material schedule.
• Body Seal, Thrust Washer and Packing: PTFE.
• Gland Nut, Stop Pin, Spring Washer and Handle: Stainless steel.
• Handle Cover: PVC.

Confirm the individual metallic grades and seat reinforcement specification when evaluating corrosion resistance, operating temperature and wear.

Typical Applications

• Skid-Mounted Systems: Local isolation around pumps, filters, dosing units and heat exchangers where installation length influences the overall layout.
• Machinery and OEM Equipment: Compact piping assemblies requiring accessible shut-off within restricted enclosures.
• Water Treatment Packages: Compatible process-water and treatment-liquid connections requiring stainless steel construction.
• Chemical Handling Installations: Selected transfer and auxiliary services after checking the fluid concentration, temperature and compatibility of all wetted components.
• Marine Auxiliary Equipment: Compatible shipboard services where available space and access are important selection factors, subject to project requirements.

Connection and Installation Requirements

Published specifications reference EN 1983 for design, EN 558-1 for face-to-face dimensions and EN 1092-1 for connections. The dimension schedule includes metric threaded mounting holes, so bolt diameter, engagement length and assembly clearance should follow the approved drawing.

For replacement projects, verify the actual installation gap, flange details and gasket arrangement. Nominal size alone does not establish dimensional interchangeability.

Pressure, Temperature and Fluid Selection

The website lists PN16–PN40 for DN15–DN50 and PN10–PN16 for DN65–DN100. Confirm the specific configuration and permissible working pressure for each ordered size.

Operating limits depend on the complete valve, including seats, packing and seals. Stainless steel compatibility should be assessed against the actual chemical composition, concentration, temperature and chloride exposure.

Use this valve primarily for on/off isolation. Sustained throttling can accelerate seat wear, while rapid closure in liquid systems may generate pressure surges. Allow sufficient space for future removal and internal servicing.
