WAFER PATTERN BUTTERFLY VALVE TYPE Z 011-A - 1

WAFER PATTERN BUTTERFLY VALVE TYPE Z 011-A TECHNICAL DATA Nominal diameter: EN 558 Series 20 ISO 5752 Series 20 API 609 Table 1 Flange accommodation: EN 1092 PN 6/10/16 ASME Class 150 AS 4087 PN 16 Flange Surface Design: Tightness check: EN 12266 (Leakage rate A) ISO 5208, Category 3 Temperature range: -40°C to +200°C (depending on pressure, medium and material) Operating pressure: A universally applicable wafer type valve acc. to EN 593. The large variety of basic materials allows applications in different industries. FEATURES - Absolutely tight sealing with flow in either direction - The valve body and disc are accurately machined which results in low operating torque and long service life and reliabililty - Triple shaft bearings prevent shaft deflection and guarantee optimum guidance even after many years of operational service - Four flange mounting holes ensure correct valve location when installing - Can be installed in any desired position - Maintenance-free - Can be disassemble, material-specific recycling possible - For paint and lacquers, a silicon-free version is available GENERAL APPLICATIONS: - Chemical and petrochemical industries - Water and waste water technology - Pneumatic materials handling technology - Shipbuilding Aluminium version. Available Sizes: DN 50 - DN 400 - Power generation industry - Transport of hazardous materials (EN 14432)
