Apollo LD-141-10-B-E-1-2 Lug Butterfly Valve 10 in

Product Description

The Apollo LD-141-10-B-E-1-2 is a 10-inch resilient seated lug style butterfly valve from the LD141 series, designed for shut-off service in industrial, commercial, HVAC, and mechanical piping systems. The body is ductile iron with an aluminum bronze disc and a 416 stainless steel stem, paired with an EPDM soft seat for reliable sealing across a wide temperature range. A gear actuator provides smooth, controlled operation at this pipe size. The valve carries a 125/150 lb pressure class rating and a top-to-inlet center dimension of 11.5 inches, making it suitable for standard ANSI flanged installations.

This valve is suited for 10-inch flanged piping systems in commercial HVAC, mechanical rooms, and industrial process applications where a durable lug-body butterfly valve is required. The lug body style allows the valve to function as an end-of-line valve when properly bolted, and the gear actuator is appropriate for the torque requirements of a 10-inch disc. The EPDM seat supports intermittent service up to 250 degrees F and continuous service up to 225 degrees F, covering typical hydronic heating and cooling applications.

Key Features

• Lug-style ductile iron body rated for 125/150 lb flanged connections per ANSI standards
• Aluminum bronze disc with 416 stainless steel stem for corrosion resistance in HVAC and industrial service
• EPDM resilient seat rated -20 to 250 degrees F intermittent and 225 degrees F continuous
• Gear actuator provides positive, controlled quarter-turn operation on a 10-inch valve
• Top-to-inlet center dimension of 11.5 inches for layout and clearance planning
• Suitable for industrial, commercial, HVAC, and mechanical piping applications

Compatibility

Designed as an OEM-style lug butterfly valve for 10-inch ANSI 125/150 lb flanged piping systems in industrial, commercial, and HVAC mechanical applications.

Installation Notes

Installation should be performed by a licensed pipefitter or plumbing professional in accordance with applicable codes including ASME B31.1 or B31.9 for piping systems. Isolate and depressurize the line completely before installation or removal. When used as an end-of-line valve, verify that lug bolting meets the manufacturer flange load requirements for the pressure class. Do not use the gear actuator handle as a lever or apply additional mechanical advantage beyond the designed handwheel.
