Flange motorized butterfly valve
The Flange Motorized Butterfly Valve from our product line serves multiple applications including potable water systems and wastewater management and seawater treatment and HVAC systems. The valve body consists of cast iron and ductile iron and aluminum stainless steel and CF8 and CF8M and CF3M materials while the disc uses stainless steel CF3M and CF3 and CF8M and nylon-coated ductile iron materials and the stem is constructed from 416 stainless steel or 304 and 316 stainless steel. The valve includes removable NBR and EPDM and PTFE and VITON and FKM* Polyurethane seats for user convenience.
The valve operates within a size range of 2” to 40” (25mm – 1000mm) and supports EN 1092 PN 6/PN10/PN16 and ASME Class 150 & AS 4087 PN 10/ PN 16 and JIS 5K/10K and ISO5211 top flange configurations. The valve operates within -30°C to + 135°C temperature range based on pressure medium and material selection which makes it suitable for various applications needing both safety and reliability features. The valve operates with electric actuators that provide 50Nm to 2000Nm torque and ON/OFF type regulation type controls which transmit 4-20 mADC 0-5 VDC or 0-10 VDC power signals through 12VDC 24VAC 24VDC 220VAC 120VAC or 380VAC 50/60Hz ±10% signals.

FAQs
What is flange butterfly valve?
The flange butterfly valve functions as a quarter-turn flow control device which consists of two main parts. The valve consists of two essential parts which include a stem-attached disc and a body section with flow ports that use an elastomeric liner for sealing. The disc moves 90 degrees inside the body structure through an external actuator which can be either a handle or motor. The valve blocks all fluid flow when it reaches a 90-degree position for closure but it provides complete unrestricted passage for liquids and gases when set at 0 degrees.
What is double flange butterfly valve?
The double flange butterfly valve functions as a flow control device which serves various industries including process operations and water treatment and power and energy sectors and additional sectors. The valves achieve tight shut-off performance at high pressure while minimizing leakage while offering an economical solution because of their basic design and affordable price.
What is a single flange butterfly valve?
The single flange butterfly valve operates as a quarter-turn rotary control valve which serves medium and high flow applications. The valve operates through disc rotation inside the body to control fluid flow between full closure and full opening positions. The single flange butterfly valve features an outer housing with two or three circular sections that bolt together to create a flanged connection on one side. The valve’s opposite end features a central shaft which connects to a gearbox or lever or actuator or electric motor for external operation.
