Product description
The Butterfly Valve, Triple-Offset, 4 in × 600# Lug, Carbon Steel + Inconel 625 Metal Seat, Gear-Operated is a triple-offset butterfly valve, 4 in, 4 in 600# ANSI Lug. Standard service rated.
Triple-offset design — the disc rotation axis is offset on three planes from the seat centerline, giving cam-action seating with metal-to-metal seal. Suitable for high-pressure, high-cycle, fire-safe, and severe-service applications where a resilient-seated wafer would not tolerate temperature, abrasion, or fugitive-emissions limits.
Construction
- Type: Butterfly — Triple-Offset
- Nominal size: 4 in
- Body material: Forged AISI 4130
- Disc material: F6NM disc + Inconel 625 metal seat
- Seat / liner material: Inconel 625 metal seat
- End connection: 4 in 600# ANSI Lug
Performance
Working pressure 1,480 psi (ANSI 600 class). Bi-directional bubble-tight shut-off; fire-safe per API 607 with optional fire-test certification. Standard service rated.
Applications
- Fire-safe HP isolation
- High-cycle abrasive service
- Refinery process plant 600# class
- Wellhead-adjacent fire-rated trees
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.
