Fugitive Emission Certified Valves in stock ISO 15848, API 622/624
Production plants generate gas emissions known as volatile organic compounds (VOCs) and hazardous air pollutants (HAPs). 60% of all fugitive emission piping systems come from valve stem packing. These gases enter our atmosphere, contributing to ozone, smog, and other organic aerosols forming. At the same time, these pollutants can hurt the environment and even cause…

APV vs LOW-COST COMPETITOR QUALITY GATE/ GLOBE VALVE
So, how does APV gate/ globe valve quality compare against its low-cost competitors? APV specifies smoothness tolerances on the stem and the stuffing box that are superior to our competitors. Many manufacturers still produce under much older versions of the API standard regarding smoothness. Of course, even the API smoothness level is an absolute base…

Sizing Actuators for all Quarter-turn Valves
Thanks to Darren Gibbons for giving us this 1994 publication as a guide to actuator sizing for all quarter-turn valves. Full credit to D.R. Stewart, formerly of Hytork. Despite the age of publication, it still, to this day, can form a basic introduction to actuator sizing. Explore the range of actuators and valves available from…

GLOBE VALVE DESIGN DISC STYLE TYPES
OPERATION Australian Pipeline Valve globe valves are for services requiring frequent operation for on-off isolation service as well as throttling. Never attempt throttling at under 20% of stem travel. Closer throttling, can result in higher pressure drops which may cause excessive velocities or cavitation and could cause vibration or high noise levels resulting in damage…

SEATING SYSTEMS FOR ABRASIVE & DIRTY SERVICE
Composite SeatingSince leather was married with timber to improve the bow, composite solutions have reduced the need to compromise. Yet most manufacturers only offer a single seat insert solution. Service considerations include temperature, media type, pressure etc. In the end materials like Nylon, Devlon and PEEK® are a compromise that must serve many masters. Hard…

Flange Tables
Online slide rule & Data sheets. Click here: https://globalsupplyline.com.au/flange-table-chart-size-as-ansi/ for our online flange slide rule.‘DN’ originates from the term ‘Diameter Nominale’. It’s a rough translation of mm for imperial sizes. It assumes that an inch is 25mm (which it’s not, it’s 25.4mm). For example a 10” flange is referred to as a 250mm in lieu…
