Many toxic, corrosive, and reactive chemicals are used in pulp and paper mills in chemical pulping. This incredibly hostile environment requires well-engineered automatic valve systems and durable valve actuators, spring units, and positioners.  Suppose you understand how paper is made and what chemicals are usually used in the atmosphere. In that case, you can instantly […]

Detecting plugs in granular material conveying chutes is difficult due to the heavy, abrasive materials and dusty, coating nature of the environment. Many technologies used to detect material movement in chutes have considerable downside. For instance, regulatory requirements and source disposal problems make nuclear gauges an unappealing choice, insertion type sensors are quickly damaged by

Ball Valves Outperform and Outlast the Alternatives MOGAS is well known throughout the power industry because they solve issues that routinely plague power plants – leaking valves, seat erosion, blown packing, and the inability to isolate critical equipment – all of which contribute to significant heat rate loss and safety concerns.

Animation of vortices* To an untrained ear, the term “vortex flowmeter” may conjure futuristic, potentially Star Wars inspired images of a hugely advanced machine meant for opening channels in warp-space. In reality, vortex flowmeters are application specific, industrial grade instruments designed to measure an important element of a fluid process control operation: flow rate. Vortex

Valves regulate fluid flow to provide accurate control and safety in any given process system, and methods of adjusting valve position are always required. Commonly, valves are operated with handwheels or levers, although some must be regularly opened, closed, or throttled. In certain conditions, it is not always practical to position valves manually; hence actuators

Hydronic variable flow systems may reset supply water temperature, pump static pressure, or a combination of both to reduce plant energy consumption and to comply with building codes and standards. The information below illustrates how valve position feedback to the Building Automation System (BAS) is used to reset the pump pressure setpoint in accordance with

Containment and smoke control dampers are applied differently and must be distinguished from one another. Containment dampers prevent the passage of fire from one zone to another. Some containment dampers have switches for maintenance indication, which is not part of the smoke control system. Smoke control dampers perform various functions: they close to help suffocate

Valve Flow Coefficient (Cv) is the flow capability of a control valve at fully open conditions relative to the pressure drop across the valve. It is defined as the volume of water (GPM in the US) at 60°F that will flow through a fully open valve with a pressure differential of 1 psi across the

Installing a butterfly valve can be tricky. This blog post is intended to serve as a guide to help you make sure that you “check all the boxes” when installing your butterfly valve, as well as some important considerations to confirm that the valve operates correctly.  We encourage you to bookmark this checklist, and to
