Common Failures of Automatic Valve
Four common failures associated with automatic valves are found at a high frequency in poorly performing control loops. These are Dead band, Stiction, Positioner overshoot, Incorrect valve sizing, and Nonlinear flow characteristic. Let’s take a closer look at each of these problems. Failure one: the valve is blocked up. The reasons are: 1. The control channel […]
Read moreFAQs in Using Valves
1. Why is the sanitary double seat valve easy to oscillate when working? For single-core, when the medium is an open type, the valve stability is good; when the medium is a closed type, the valve stability is poor. The double seat valve has two spools, the lower spool in the flow closed state, and the […]
Read moreWhat are the Common Connection Types of Valves?
1. Flange connection This is the most used connection type of valve. According to the shape of the contact surface, it can be divided into the following subtypes: 1) Smooth type: it’s used in valves of pressure that is not high. The processing is rather convenient. 2) Concave and convex type: the operating pressure is […]
Read moreLarge Diameter Sanitary Butterfly Valve Leakage Reasons
Large-caliber sanitary butterfly valve leakage sometimes occurs during use. Due to the large diameter butterfly valve size being relatively large, so it is time to pay special attention to the installation and maintenance. So what are the reasons for large diameter sanitary butterfly valve to leak? It has two aspects. 1. Butterfly valve itself quality […]
Read moreThe Proper Ways to Clean the Filth of Hydraulic Valve
Many users don’t have problems with the use of hydraulic valves. But they don’t have a clue about the subsequent maintenance and cleaning. Here is the introduction to the cleaning technology of hydraulic valves. How do you clean hydraulic valves? Note the following when we do the cleaning Filth of the Hydraulic Valve: 1. For […]
Read moreHow to Maintain a Sanitary Butterfly Valve?
Sanitary butterfly valves, like other mechanical products, also require maintenance. By doing this work well, the service life of the valve can be extended. Here, Adamantvalves will introduce the maintenance of sanitary butterfly valves. 1. During the application of the sanitary butterfly valve, it should always be kept clean. The driving thread must be lubricated […]
Read moreThe Working Temperature Range of the Valve Rubber Seals
Owners of various food industries and those who work there have a better understanding of the thermal conditions that surround such places. The sanitary valves used in such places should therefore have rubber seals that can withstand a wide temperature range. When buying rubber seals for these valves, it is good to understand various thermal requirements in […]
Read moreThe Problem of High Noise Level of Valves
One of the most obvious and uncomfortable problems with valves is noise. For human beings, noise can not only interfere with life but also lead to permanent hearing loss and an unsafe working environment. Studies have shown that long-term exposure to high levels of noise will cause damaged hearing in human beings. Hearing damage is […]
Read moreMaintenance of the Sanitary Pump
The review of sanitary pump repair records and MTBF is of great importance to responsible and conscientious pump users. For convenience, these failure statistics are often translated into MTBF (in this case, the installed lifetime before the failure). Unplanned maintenance is often one of the most important property costs, and failures of mechanical seals and […]
Read moreValves Components and Operating Principle
As a common piece of equipment in fluid processing facilities, sanitary valves are different in types, shapes, and sizes. However, they all basically consist of some of the parts defined as follows: Body: the framework that holds everything together and serves as the pressure boundary. Bonnet: the cover on the valve body. During valve manufacturing, the […]
