Introduction

High performance butterfly valve, in add ition to the conventional valve had to adapt to the working condition of the medium according to different medium, chose different structure material and special processing, can also be used for cryogenic, vapor, chlorine gas, oxygen high vacuum, corrosion and other special conditions.

Features

1、Fire-proof structure
Fire-proof valve is tested to API 607 4th Edition and BS 6755 Part II

2、Fixed axis
Fixed collar is installed in the top of axis,2“-24“(N50-600), when axis breaks accident, avoid the upper part to move out of gland.

3、Provide ce marked versions available
CE marked and documented valves that conform to the European Pressure Equipment Directive(PED)97/23/EC are available in ANSI Class 150,300, both standard and Fire-Tite construction. Operating torques, construction potions and valve dimensions are exactly the same as the standard ANSI 150/300 offering

4、Convenient to maintain and upkeep valve seats
Replace axis only by taking inserts down, without disassembling disc and axis

5、Excellent for both On-Off and Control Application
(1)Superior control characteristics.
(2)Inherent flow characteristic is modified equal percentage
(3)Wide rangeability
(4)Tight shut-off even in control applications
(5)Standard lugged style valves are suitable for bidirectional dead-end service at the full pressure temperature rating of the valve

6、Single-Source Responsibility
(1) Purchase valves, actuators, and accessories, completely mounted from one source.
(2) Available with electric, manual gear, and pneumatic double acting or spring return actuators and a variety of accessories including limit switch,solenoids, and positioners.
(3)OEM services available through world-wide service centers.

7、Available in a Wide Choice of Material for a Broad Range of Applications
Standard body materials include ductile iron, aluminium bronze, carbon steel, stainless steel, Monel, Alloy 20. Users can also, according to requirements select other materials
