The high-performance butterfly valve is a new type of butterfly valve designed on the basis of absorbing the advantages of several different structure butterfly valves. The sealing surface of the valve plate of this butterfly valve is a spherical arc surface body. The sealing mechanism achieves a real dynamic seal through the system pressure, so it has excellent cutting performance and durability. Its small size, light weight, wide manufacturing range and easy maintenance. The high-performance butterfly valve is mainly suitable for the drainage of water plants, power plants, steel smelting, chemical engineering, water source engineering, environmental facility construction, etc., especially suitable for water pipelines, as regulating and intercepting equipment.

A double offset butterfly valve is an HPBFV rated for ANSI (285 @ 100F or 100 psig @ 400F for 150# ANSI) rated applications. For this type of valve, the disc and stem are double offset, (set back behind the disc and to the side) causing the disc to rotate into place upon closure without significant seat contact. Different from an RSBFV, the stem is located behind the disc, which enables the disc to “rub” over the seat in the last 10% of travel, during the 90-degree rotation.

This seat usually is some type of Reinforced Teflon or for high temperatures above 450F, the seat can be metal, usually a hardened metal, like Stellite. The most user-friendly allow removal/replacement of the stem, disc, and seat without welding.

FEIDA is specialized in High Performance Butterfly Valve for more than 15 years. There are 2 main facilities includes 2 valve assembly & testing factories, 1 large CNC machinery plant, 1 investment casting foundry (3000T/Y) and 1 valve R&D center, equipped with most advanced production equipment and testing equipment.

FEIDA VALVE is the top ranking China double offset butterfly valve manufacture. The annual output of high performance butterfly valve is more than 100,000,000 set.

The fire safe butterfly valve is also in FEIDA VALVE product range. Our fire safe butterfly valve is certificated by American Petroleum Institute (API) according to API 607 standards.

In the dustless workshp,FEIDA also produce the food-grade valves. FEIDA food-grade valve is certificated by Food and Drug Administration United States (FDA).
