UPVC Butterfly Valve

UPVC Butterfly Valves are popular because of their dependability and low maintenance needs. Manufactured from unplasticized polyvinyl chloride (UPVC), these valves offer outstanding resistance to corrosion, chemicals, and moisture, making them ideal for handling aggressive fluids where metal valves may fail or require frequent replacement. Their durable thermoplastic construction reduces wear on internal components, which helps extend the service life of pneumatic actuators used with butterfly valves. This results in lower operating costs, reduced downtime, and minimal maintenance effort, making them a cost-effective choice for long-term industrial applications.

Types & Connections

UPVC Butterfly Valves are available in multiple designs and connection options to suit a wide range of industrial piping systems. Selecting the right type and connection ensures reliable sealing, easy installation, and long-term operational efficiency.

Types of UPVC Butterfly Valves

Wafer Type UPVC Butterfly Valve
Wafer type valves are designed to fit between two pipe flanges and are held in place using long bolts. These valves are lightweight, compact, and cost-effective, making them ideal for systems where space is limited and frequent maintenance access is required.
Lug Type UPVC Butterfly Valve
Lug type valves feature threaded inserts (lugs) around the valve body, allowing them to be bolted directly to pipe flanges. This design enables one side of the pipeline to be disconnected without disturbing the other side, making lug type valves suitable for isolation and maintenance-friendly installations.
Gear Operated UPVC Butterfly Valve
These valves are equipped with a gearbox that allows smooth operation in larger pipe sizes or high-flow systems. Gear-operated UPVC butterfly valves provide precise control with minimal operator effort, making them ideal for industrial flow regulation.

Actuated valves are fitted with pneumatic or electric actuators for automated operation. These valves are commonly used in process automation systems where remote control, consistent operation, and integration with PLC or SCADA systems are required.

Connection Types of UPVC Butterfly Valves

Flanged End Connection
Flanged connections provide strong mechanical strength and leak-proof sealing. They are widely used in industrial pipelines where secure mounting and alignment are critical.
Wafer Mount Connection
Wafer-mounted valves are sandwiched between two flanges, offering easy installation and reduced space requirements. This connection type is ideal for compact industrial layouts.
Lugged Connection
Lug connections allow bolting on both sides independently, enabling pipeline section isolation. This is especially beneficial in maintenance-intensive systems.
Actuator Mounting (ISO Standard)
UPVC butterfly valves are designed with ISO-standard actuator mounting pads, allowing easy integration with pneumatic and electric actuators without modification.
