Butterfly Valve Lug Type Lever Handle: Premium Flow Control Solution
Engineered for precision, ERA's Handle Type Butterfly Valve features a lightweight, corrosion-resistant polyvinyl chloride (PVC) body. Operated manually via a robust lever handle, it enables smooth quarter-turn operation for precise flow control. Key design elements include a rotating disc, choice of EPDM or Viton seals (for optimal chemical resistance), and a sturdy handle lock to secure positions. This Handle Type Butterfly Valve delivers zero-leakage performance and is ideal for low-pressure systems handling acids, alkalis, water, and compatible fluids. Available in sizes DN15-DN300 (½"–12"), ensuring broad application suitability.

Why Choose ERA's Handle Type Butterfly Valves?
Production Excellence
Advanced Fabrication: CNC-machined PVC components guarantee dimensional accuracy and leak-proof assembly.
Custom Solutions: Valves tailored to specific pressure ratings (PN6-PN16), end connections (flanged, wafer, threaded - including BS Butterfly Valve (Handle Type) flange standards), and seal materials.
Rapid Prototyping: 15-day lead time for bulk orders with no Minimum Order Quantity (MOQ) restrictions.
Rigorous Quality Control
Material Testing: Only ISO 9001 compliant, certifiable PVC raw materials with anti-UV stabilization are used.
Performance Checks: Every valve undergoes hydrostatic pressure tests (1.5x rated pressure) and torque validation for consistently smooth disc rotation.
Traceability: Batch-specific documentation provided for full quality assurance.
Unmatched Service & Support
Technical Support: On-demand access to CAD drawings, detailed installation guides, and comprehensive chemical compatibility charts.
Global Logistics: Efficient FOB Taizhou port shipping with real-time tracking for reliable delivery.
Warranty: Backed by a 2-year warranty and 24-hour response commitment for replacements.
Expert Selection Guide
Fluid Compatibility: EPDM seals recommended for water/alkalis.
Size & Pressure: Match valve DN size precisely to pipe diameter. Verify PN rating suitability (e.g., PN10 for 10-bar systems).
Handle Configuration:> Standard lever handle enables quick shutoff; gearbox handles available for high-torque applications.
Certifications: Specify NSF/ANSI 61 certification essential for potable water applications.
Installation: Install between flanges using appropriate gaskets; critical to ensure disc rotation direction aligns correctly with flow. The Lug Type lever handle design simplifies positioning.
