How To Install a Safety Valve?
Always use correct installation techniques and take necessary precautions when installing a safety valve. Proper safety valve installation is critical to the safety of your employees and your fluid or air-gas processing system. Where Should a Pressure Relief Valve be Installed? The safety valve should be installed as close as possible to the protected equipment […]
Read moreKey Features of the Best High-Temperature Ball Valves
What are the main features of high-temperature ball valves? Ball valves designed to withstand and perform in high-temperature applications are critical components of many industrial processing systems. Precision engineered and purposefully built, high-temperature ball valves require strict material selection for each component, specialized treatments, and thorough coatings to achieve the mechanical strength required to negate […]
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 moreCommon 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 moreThe Selection of the Size and Type of Butterfly Valve
The butterfly valve has a short structural length and overall height. Its speed of opening and closing is quick. It has good fluid control characteristics. Structurally, the butterfly valve is most suitable for the production of a large diameter valve. When the butterfly valve is used to regulate the flow, the most important thing is […]
Read moreWhat is Mounted Ball Valve?
What is a mounted ball valve? The mounted ball valve is widely used in petroleum and natural gas pipelines, as well as in petroleum refining, petrochemical, chemical, chemical fiber, metallurgical, electric, nuclear, food, and other devices. It’s easy and quick to remove the mounted ball valve from the pipelines. And the maintenance is also easy […]
Read moreThe Classification of Steel Gate Valves
What are the types of gate valves? Gate valves can be divided into two main types: Parallel and wedge-shaped. The Classification of Steel Gate Valves 1. According to the structure of the gate plate 1) Parallel gate valve: the sealing surface is parallel to the vertical centerline. Two sealing surfaces are parallel to each other. A […]
Read moreThe Overview of Internal Thread Connection Ball Valve
The internal thread connection ball valve can be divided into integral type (one-piece), two-piece type, and three-piece type. The casting of the valve body uses an advanced technique so that the valve’s structure is reasonable and appears beautiful. The valve seat uses an elastic sealing structure. The sealing is reliable and the opening and closing […]
Read moreThe Introduction of Ball Valve Applications
What are the applications of ball valves? Since the ball valve usually uses rubber, nylon, and PTFE as sealing ring materials of the valve seat, its operating temperature is limited by the sealing ring materials of the valve seat. The shut-off effect of the sanitary ball valve is achieved by a metal sphere pressing tight against the […]
Read moreThe Classification of Ball Valves by Structural Types
There are five general body styles of ball valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve—especially the casing that contains the ball itself—are manufactured and assembled. The valve operation is the same in each case. The classification of ball valves by structural […]
