Reliable Sealing Performance – Bubble-tight shutoff with resilient seating ensures leak-free performance for liquids, gases, and chemicals.
Wide Temperature & Pressure Range – Suitable for diverse operating conditions across multiple industries.
Low Maintenance Design – Robust mechanical construction with no electrical components reduces downtime and maintenance costs.
Versatile Applications – Ideal for water supply, chemical processing, oil and gas pipelines, HVAC systems, food processing, and pharmaceutical industries.
The Stainless Steel Manual Lock Wheel Butterfly Valve operates on a quarter-turn mechanism. The valve consists of a circular disc (butterfly plate) mounted on a stem, which is connected to the handwheel operator.
When the handwheel is rotated, it drives the stem to turn the disc by 90°. In the closed position, the disc is perpendicular to the flow path, creating a tight seal against the valve seat. In the open position, the disc is parallel to the flow, allowing unrestricted fluid passage.
The locking mechanism integrated into the handwheel allows the operator to secure the valve at any position – whether fully open, fully closed, or any intermediate throttling position-. This is achieved through a locking wheel or lever that engages with a notched plate, preventing unintended movement caused by flow forces or vibration.

Q: What materials are available for this manual butterfly valve?
A: Available in SS304 (1.4301) and SS316L (1.4404) stainless steel for excellent corrosion resistance.
Q: How does the locking mechanism work?
A: The integrated locking wheel or lever engages with a notched plate, allowing the valve to be securely locked at any desired position – fully open, fully closed, or any intermediate throttling position.
Q: What is the operating temperature range?
A: The valve operates across a wide temperature range suitable for industrial applications, typically from -20°C to 120°C depending on the sealing material selected.
Q: What industries use this stainless steel butterfly valve?
A: Widely used in water treatment, chemical processing, oil and gas pipelines, HVAC systems, food and beverage processing, pharmaceutical, and marine industries.
Q: What connection types are available?
A: Available in wafer type and lug type designs for easy installation between flanges.
Q: Is this valve suitable for throttling (flow regulation) applications?
A: Yes. The handwheel operator enables precise throttling control, and the locking mechanism secures the valve at the desired flow position.
Q: Does the valve require electrical power?
A: No. This is a purely manual valve operated by the handwheel, requiring no electrical or pneumatic power – ideal for locations where automation is not required or available.
Q: What size range is available?
A: Available in sizes from DN40 to DN1200 (1.5" to 48") to suit diverse pipeline requirements
