Center Line LT Lug Butterfly Valve Soft Seal Manual Control for Water
Key Features
- LT Lug Design: Unique lugged body allows for "dead-end service" (installing at the end of a pipe) or standard installation between flanges using short bolts.
- Easy Manual Operation: Equipped with a ergonomic lever handle with a 10-position lock, ensuring precise flow control and secure locking.
- Bubble-Tight Sealing: Features a replaceable EPDM/NBR rubber seat that provides zero-leakage performance and excellent corrosion resistance.
- Durable Construction: Heavy-duty Cast Iron/Ductile Iron body with a fusion-bonded epoxy coating (blue) for superior protection against rust and harsh environments.
- Centerline Disc: The nickel-plated ductile iron or stainless steel disc ensures smooth 90° rotation and long service life.
Product Description
Product Images & Details
1. Robust Body & LT Lugs
The valve body is constructed from high-grade Cast Iron or Ductile Iron. The distinct "ears" (lugs) on the sides are threaded, allowing for secure connection to pipeline flanges. This design supports independent installation on either side, adding flexibility to your piping system.
2. High-Performance Lever Handle
The manual lever is designed for safety and ease of use. It features a 10-position locking mechanism (often every 10 degrees) that allows you to fix the valve opening at precise angles to regulate flow. The handle can often be removed or adjusted to prevent unauthorized operation.
3. Precision Disc & Soft Seat
- Disc: Made of Ductile Iron with Nickel Plating or Stainless Steel (SS304/316), offering excellent resistance to wear and corrosion.
- Seat: The replaceable EPDM (Ethylene Propylene Diene Monomer) or NBR (Nitrile Butadiene Rubber) seat ensures a tight seal against the disc, preventing leaks even after thousands of cycles.
