Butterfly Valve, Lug Style, 10 in × 150# Lug, Ductile Iron + Buna-N Seat, Gear-Operated

The Butterfly Valve, Lug Style, 10 in × 150# Lug, Ductile Iron + Buna-N Seat, Gear-Operated is a lug style butterfly valve, 10 in, 10 in 150# ANSI Lug. Standard service rated.

Lug-style body — threaded lug holes accept stud bolts directly into the valve body, allowing dead-end service and downstream-flange removal without depressurising upstream. Slightly heavier and more expensive than wafer-style but operationally more flexible.

Construction

• Type: Butterfly — Lug Style
• Nominal size: 10 in
• Body material: Cast ductile iron (ASTM A536)
• Disc material: Ductile iron disc
• Seat / liner material: Buna-N (NBR) seat
• End connection: 10 in 150# ANSI Lug

Performance

Working pressure 232 psi (ANSI 150 class). Suitable for isolation and on/off service; throttling service with the optional positioner / actuator package. Standard service rated.

Applications

• Tank-farm bulk transfer mains
• Crude / condensate pipeline cross-overs
• Large-bore water mains
• Refinery utility headers

Compliance

• API 609
• Mill test reports per EN 10204 3.1 / 3.2

How to order

Confirm (a) line working pressure, (b) flange class, (c) service medium (clean water / clean hydrocarbon / abrasive slurry / sour gas — drives seat material selection), (d) operating temperature range (drives elastomer / metal-seat selection), (e) operation type (lever / gear / actuated). Indus quotes ex-works OEM with applicable certifications.

Companion products

For dead-end / downstream-isolation service, specify lug-style. For high-pressure or fire-safe service, specify triple-offset metal-seated. Pair with matching ANSI raised-face flange gaskets and bolting per ASME B16.5. For automated service, Indus supplies pneumatic and electric actuators with the matching ISO 5211 mounting bracket on request.
