Butterfly Valve Sleeve

Description

Butterfly Valve Sleeve – High Performance Sealing Solution for Industrial Applications

In modern piping systems, sealing integrity is not optional — it is mission-critical. The Butterfly Valve Sleeve plays a central role in ensuring zero leakage, chemical resistance, and long service life in butterfly valve assemblies. Whether deployed in water treatment plants, chemical processing lines, pharmaceutical production, food industries, or slurry handling systems, the sleeve acts as the primary resilient sealing element between the valve body and disc.

At Krishna Industries, we specialize in manufacturing and supplying precision-engineered Butterfly Valve Sleeves designed for durability, dimensional accuracy, and long-term operational reliability. Our sleeves are compatible with Rubber Lined Butterfly Valve, PTFE Lined Butterfly Valve, Wafer Type Butterfly Valve, Lug Type Butterfly Valve, and Industrial Butterfly Valve assemblies across multiple pressure classes.

With deep industry experience and strong distribution capability, Krishna Industries is recognized as a trusted Supplier, Wholesaler, Exporter, Distributor and Trader of Butterfly Valve Sleeves from Ahmedabad, Gujarat, India. We focus primarily on Indian industrial buyers while also serving export requirements with quality compliance and structured documentation.

Minimum Order Quantity (MOQ)

• MOQ: 10 Pieces
• Flexible bulk pricing available for Indian industrial buyers

What is a Butterfly Valve Sleeve?

A Butterfly Valve Sleeve is a molded elastomer or polymer liner installed inside the valve body. It provides:

• Primary sealing against the disc
• Body protection from corrosive media
• Bidirectional sealing capability
• Shock and vibration absorption
• Reduced torque operation

Unlike metal-to-metal seated valves, butterfly valve sleeves create resilient seating that ensures bubble-tight shutoff even under fluctuating pressure conditions.
