Schubert & Salzer – Type 6051 – Aseptic Right Angle Valve

Overview

The Schubert & Salzer Type 6051 is a pneumatic aseptic right angle control valve designed for sterile flow control in pharmaceutical, biotechnology, and food & beverage applications. Available in sizes 1/2″ through 2-1/2″, the valve features a 316L stainless steel barstock body, a reinforced EPDM diaphragm with PTFE fluid-side lining, and an integrated digital positioner (Type 8049) for precise modulating control. It is also available as a shut-off valve without a positioner.

The Type 6051 carries EHEDG (European Hygienic Engineering & Design Group) certification and is fully compliant with FDA requirements, USP Class VI, and EU regulations (EG) 1935/2004 and (EU) 10/2011. The right angle body design promotes optimized flow conditions, consistent wall shear stress, and easy cleanability, making it well-suited for CIP (Clean-in-Place) and SIP (Steam-in-Place) processes.

Features & Benefits

• EHEDG-certified right angle body design promotes high wall shear stress and optimal cleanability for CIP/SIP processes
• 316L stainless steel barstock body is non-porous, corrosion resistant, and compatible with aggressive cleaning agents
• Composite diaphragm — reinforced EPDM with fluid-side PTFE foil — provides high chemical resistance and positive media isolation from the actuator
• Integrated digital positioner Type 8049 supports 2-wire and 4-wire configurations, IO-Link, and an integrated process controller (IPC) option
• PEEK control plug delivers excellent chemical resistance and long service life in demanding sanitary service
• Solid diaphragm construction is rated for extreme temperature cycling, including steam sterilization service
• Suitable for vacuum applications down to 0.0295 in Hg
• Optional explosion-proof (Ex) configuration available: ATEX non-electrical II 3G/2G Ex h IIC T6–T3 X Gc/Gb and II 3D/2D Ex h IIIC 85°C–140°C X Dc/Db
• Optional fully stainless steel positioner housing available for high-washdown or all-stainless installations
• EC Declaration of Conformity and UKCA Declaration of Conformity included
