Ball Valves

AquaFlow Floating Ball Valve

Bi-directional floating ball valve for tight shut-off — DN15–DN300, Class 150–600.

A blow-out-proof, fire-safe floating ball valve engineered for isolation duty across water, hydrocarbon and process lines. Forged or cast bodies, mirror-finish balls and low-friction seats deliver bubble-tight sealing at low operating torque — actuator-ready out of the box.

Overview

Isolation you can specify anywhere on the line.

The AquaFlow floating ball valve provides positive, bi-directional isolation for water treatment, oil & gas, power, chemical, HVAC and desalination service. A quarter-turn takes it from full bore to bubble-tight shut-off, with a seating design that uses line pressure to improve the seal rather than fight it.

Every valve carries a blow-out-proof stem loaded from inside the body, a secondary metal-to-metal fire-safe seat to API 607, an anti-static device linking ball, stem and body, and cavity self-relief to release thermally expanded media — the four features that separate a duty valve from a commodity one.

Construction

Engineered part by part.

Ball valve body and bonnet
01

Body & Bonnet

Cast (ASTM A216 WCB) or forged (A105 / A350 LF2) bodies with a bolted or one-piece bonnet. CF8 / CF8M stainless, LCC, duplex and nickel alloys for corrosive and cryogenic duty.

Precision-ground ball and blow-out-proof stem
02

Ball & Stem

Precision-ground, hard-chrome or ENP-coated ball gives a mirror seating finish. The blow-out-proof stem is loaded from inside the body — line pressure cannot eject it.

Seat and seal set
03

Seats & Seals

PTFE, RPTFE, Devlon or PEEK soft seats for bubble-tight shut-off, or Stellite metal seats for high-temperature and abrasive service, with fire-safe secondary metal seating to API 607.

ISO 5211 actuator mounting pad
04

Operation / Actuation

Lever, gearbox, pneumatic or electric actuation on a standard ISO 5211 mounting pad. Anti-static device, locking handle, limit switches and cavity relief available as options.
