Overview

Engineered for severe-duty process isolation and throttling, this double-offset butterfly valve delivers bubble-tight shut-off with metal or lined seats. Compact, lightweight, and rated for high-pressure and high-temperature service across Oil & Gas, petrochemical, and power applications.

// WHY OPERATORS CHOOSE IT //

Proven double-offset geometry delivers reliable shut-off across millions of cycles. Compact footprint reduces installed weight by up to 70% vs. gate valves, cutting structural and piping costs.

// COSMOS DIFFERENTIATOR //

We don't just supply valves — our engineers size, select, and support every butterfly valve with actuation packages, torque calculations, and field commissioning.

// 02 — KEY FEATURES //

Engineered
where it matters

01

Double-offset design

Reduces seat wear and operating torque, extending service life in high-cycle applications.

02

Metal & lined seats

Choose metal-seated for high temperature or lined (PTFE/RPTFE) for chemical service — both deliver Class VI shut-off.

03

Compact & lightweight

Up to 70% lighter than equivalent gate valves, reducing pipe stress and support structure costs.

04

Fire-safe certified

API 607 fire-safe design with secondary metal seat backup for upstream and refinery isolation.

05

Bi-directional shut-off

Equal sealing performance in both flow directions — no orientation constraints during installation.

06

Automation ready

Designed for pneumatic, electric, or hydraulic actuation with ISO 5211 mounting.
