SBP Butterfly Valves

DN 25 - DN 1000 | NPS 1" - 42"

The SBP plastomeric butterfly valve is suitable for shutting off, regulating, and throttling corrosive process media in liquid, powder, or gaseous form. Its compact design, available with various lining options, ensures reliable adaptation to different media and process requirements. The valve is also suitable for use under vacuum.

Main Features

Rugged, compact design

The robust design with compact dimensions allows for space-saving installation and ensures a high level of operational reliability.

Completely gas-tight and suitable for vacuum applications

The reliable seal ensures absolute gas tightness across the entire pressure and temperature range and allows for use under vacuum.

High-Quality Lining and Disc Materials

A wide selection of high-quality materials for linings and discs allows for optimal adaptation to various corrosive and demanding process media.

Maintenance-free shaft seal

The sophisticated shaft seal design ensures reliable and maintenance-free operation, even at high operating pressures and in automated process systems.

One-piece disc/shaft

The proven one-piece disc/shaft design with a polished disc sealing lip ensures hysteresis-free control characteristics and precise actuation.

Operating Conditions

depending on the choice of material
Pressure Range 1 mbar to 16 bar
0.01 psi to 232 psi
Temperature −40 °C to +220 °C
−40 °F to +446 °F

The SBP butterfly valve features a robust and compact design with a small footprint, making it ideal for the reliable shutoff and control of demanding process media. The high-quality lining and robust disc ensure high resistance to corrosive and aggressive media.

The sophisticated shaft sealing concept ensures a reliable and maintenance-free seal across the entire pressure and temperature range. The one-piece disc/shaft assembly with a polished disc sealing strip enables hysteresis-free control characteristics and precise actuation. Thanks to the chambered sealing strips, no additional flange gaskets are required. The SBP is designed for installation between flanges in accordance with DIN PN10 / 16 and ANSI 150 lbs and is therefore suitable for a wide range of industrial applications.
