Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...

MINOTAUR series replaceable seat high performance butterfly valve
In modern oil, gas, and water pipeline systems, reliability and maintenance efficiency are critical. One of the key components ensuring smooth operations is the pig launching and receiving system.
RKSfluid delivers customized pig launchers & receivers tailored to your pipeline needs—covering onshore facilities to offshore platforms for comprehensive application.
RKSfluid® offers a complete service from design to manufacturing, fully compliant with ASME standards.
What Are Pig Launchers & Pig Receivers?
The pig launcher and receiver is an essential component in long-distance pipeline systems, designed to safely launch and receive pipeline pigs without interrupting the flow.
They are used to deploy and retrieve "pipeline pigs" - mechanical tools that travel inside pipelines to clean, inspect, or segregate fluids.
This process, known as pigging, helps remove debris, wax buildup, or scale, ensuring clean and efficient pipeline performance.
With a modular structure and robust corrosion and pressure resistance, it can be customized for different pipeline requirements.
Why Do Pipeline Operators Need Pigging Systems?
Without regular pigging, pipelines may face:
By implementing pigging systems, operators benefit from:
