IP87 Digital Electro-Pneumatic Valve Positioner

Posted by Baelz North America on Apr 25, 2019 7:32:36 AM

The IP87 digital electro-pneumatic valve positioner is one of our new products for 2019. It acts as a digital positioner that works with a pneumatic actuator to correctly set valve positions according to the control signal. This minimizes the effects of friction and other factors that could impact a valve’s performance. It uses a 4–20-mA input and output for both the control and feedback signal.

Baelz North America ANSI Valves

Posted by Baelz North America on Jan 7, 2019 1:35:54 PM

The American National Standards Institute (ANSI) sets rules and guidelines regarding the most critical technical aspects of various components manufactured for industrial use in North America. All ANSI-compliant Baelz valves are also compliant with ISA specifications. This is due to the International Society of Automation’s (ISA) reaffirmation of existing ISA valve-related standards, which include ANSI valve standards.

2-Way vs 3-Way Valves: Which Type is Right for You?

Posted by Baelz North America on Oct 10, 2018 10:48:00 AM

Valves play a crucial role in almost all industrial processes. These devices regulate, redirect, or control the flow of liquids or gases by opening, closing, or partially blocking flow passages. There are numerous types of valves, each differing in various ways, including operating principle, configuration, power source, and application.

Linear Valve Actuators: Precision vs. Speed

Posted by Baelz North America on Jul 17, 2018 11:34:00 AM

Linear valve actuators are connected to a control valve to create motion that will perform the open/close valve operation. This motion can either be pneumatically or electrically generated, depending on the type of actuator in use. Some industrial processes may require electric linear actuators for precision valve control, while other processes employ pneumatic linear actuators which can rapidly execute valve operation.

The American National Standards Institute (ANSI) is a nongovernment, nonprofit organization that coordinates U.S. industry standards with international standards so that U.S. products can reach the global market. In essence, ANSI serves as an accreditation body for standards developed by other organizations, companies, consumer groups, and government agencies.

The Deutsches Institut für Normung (DIN), or the German Institute for Standardization, serves a similar function. However, DIN is a government organization that embodies German concerns within the framework of European and International standards. DIN has a wide reach, and over 30,000 DIN standards provide comprehensive coverage for various products and technologies.

Component Highlight: Baelz Actuators

Posted by Baelz North America on Apr 3, 2018 11:32:43 AM

Thrust, speed, power, and precision: the right actuator is a key element of equipment performance in applications across almost all industries. Heavy duty manufacturing plants, marine industries, as well as automotive plants all rely on specialized actuators.

Baelz offers a complete line of actuator solutions, with emphasis on two major types: electric and pneumatic. The most recent specialty addition, the E65 model, is the first to feature a spring assisted fail position with either an open or closed solution.

3-Way Valves Vs. 2-Way Valves in a Chilled Water Systems

Posted by Baelz North America on Apr 1, 2017 12:34:00 PM

Regulating the flow of a fluid by varying the size of the opening through which the chilled fluid passes, chilled water control valves are key components in fluid pipelines. In general, control valves consist of an electronic controller, which houses the modulating elements; a positioner, which determines the degree to which the valve opens; and an actuator, which initiates the mechanical movement of the controlling element. As a critical part of any fluid pipeline, the control valve helps regulate the fluid flow between the minimum requirement and the maximum installed capacity of the pipeline. These valves are often referred to as final control elements.

The Relationship Between Valve Chatter and Control Valve Orientation

Posted by Baelz North America on Nov 15, 2016 9:36:23 AM

Valve Chatter

As systems expand and become more complex, the cause behind maintenance issues can vary – particularly with valves. During the course of valve management and maintenance, it’s likely that every technician will hear the familiar sounds of valve chatter.

Chattering is more than an auditory nuisance. Left unaddressed, chatter can and will lead to damaged valve components, reduced valve lifespan, costly downtime, and potential system-wide failure.
