Product description
The Butterfly Valve, Wafer Style, 4 in × 150# Wafer, Ductile Iron + Buna-N Seat, Lever is a wafer style butterfly valve, 4 in, 4 in 150# ANSI Wafer (between flanges). Standard service rated.
Wafer-style body — fits between matching ANSI flanges with through-bolts. Lower cost and lighter than lug-style. Cannot be used in dead-end service; bolted up and downstream simultaneously.
Construction
- Type: Butterfly — Wafer Style
- Nominal size: 4 in
- Body material: Cast ductile iron (ASTM A536)
- Disc material: Ductile iron disc
- Seat / liner material: Buna-N (NBR) seat
- End connection: 4 in 150# ANSI Wafer (between flanges)
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
- Cooling-water main headers
- Tank-farm transfer mains
- Process water bulk lines
- Hydrocarbon utility (clean)
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.
