Butterfly Valve Lug Type JIS 5K

TECHNICAL DESCRIPTION

Butterfly valve, soft-sealing, centric with one-piece “LUG” type stem. The sealing element is a rubber cuff, vulcanized to the body. Top flange according to ISO 5211.

The vulcanized cuff allows the valve to perform its functions even at negative pressure values (vacuum).

WORKING FLUID / MEDIUM

• Fuels, lubricating oil and flammable hydraulic oils,
• Petrol, air, gas, non-flammable hydraulic fluids, boiler feed water, condensate.
• Drinking water
• Sea water.

EXECUTION

• Disc made of stainless steel AISI 316.
• Seal – rubber EPDM or NBR, (FPM/FKM on request).
• Other materials on request.

OPTIONS

• Manual drive
• Gearbox drive
• Electric or pneumatic drive.

Dimensions: DN 200 – 600


Description

The JIS 5K Lug Type Butterfly Valve is engineered for high-performance flow control in demanding industrial applications. Designed in compliance with JIS (Japanese Industrial Standard) 5K pressure rating, this valve ensures reliable operation and durability under moderate pressure conditions. Its lug-type design allows for easy installation and removal from piping systems without disassembling adjacent components, making it ideal for maintenance-intensive environments.Constructed from robust materials, the valve features a disc that rotates 90 degrees to regulate or shut off fluid flow, providing efficient and quick operation. The lug-type configuration offers enhanced structural integrity and is suitable for end-of-line service. Common applications include water treatment plants, chemical processing, HVAC systems, and general industrial piping where secure, leak-proof performance is critical.Key features include:Compliance with JIS 5K standards for pressure and dimensionsLug-type body for easy installation and system isolationDurable disc and seat materials for long service lifeCompact and lightweight design reducing space and support requirementsSuitable for handling water, air, and other non-aggressive fluidsThis valve is an excellent choice for engineers and procurement specialists seeking a cost-effective, high-quality solution that meets stringent industrial standards. Its design minimizes pressure drop and ensures smooth operation, contributing to overall system efficiency and reduced operational costs.
