Schubert & Salzer – Type 7033 Pad Mounted Valve for Valve Block

Overview

The Schubert & Salzer Type 7033 is a pneumatically operated stainless steel pad-mounted valve designed for safe shut-off of normal and aggressive media in valve manifold block installations. Available in sizes 3/8″, 1/2″, 3/4″, and 1-1/4″, the Type 7033 mounts directly onto valve blocks, eliminating the need for pipe fittings and reducing potential leak points in compact process assemblies.

Rated to PN 40 with a stainless steel CF8M body, the Type 7033 handles gases, vapors, and liquids across a media temperature range of -22°F to +392°F, with extended application capability from -148°F to +428°F. Multiple actuator options and special versions — including low temperature, pressure balanced, degreased, silicone-free, and PTFE-free — are available for demanding service conditions.

Features & Benefits

• Pad-mounting connection eliminates pipe fittings at the valve block interface, reducing assembly complexity and potential leak points
• Compact size range of 3/8″, 1/2″, 3/4″, and 1-1/4″ for use in space-constrained valve manifold assemblies
• Stainless steel CF8M body for compatibility with normal to aggressive media including gases, vapors, and liquids
• Rated to PN 40 with media temperatures from -22°F to +392°F
• Extended application temperature range of -148°F to +428°F for low-temperature and high-temperature service
• Pneumatically operated with choice of piston or stainless steel diaphragm actuator
• Actuator body options in brass (chrome plated), stainless steel, or polymer
• Optional ATEX non-electrical approval (II 2G Ex h IIC and II 2D Ex h IIIC) for hazardous area installations
• Special versions available: low temperature, pressure balanced, degreased, silicone-free, and PTFE-free
• Accessories including limit switch, pilot valve, manual override, and stroke limiter available from factory
• EC and UKCA Declarations of Conformity available
