What is the electric three-ball valve

July 29 21:00:49, 2024

Electric three-piece threaded ball valve small size, electric three-piece ball valve is composed of three parts of the valve housing, the four longer bolts from both ends of the middle of the valve body and valve ball made. The advantage is that without removing the pipe thread for disassembly and dismantling, the four bolts can be removed directly, and the middle part of the valve body can be removed. The working principle is also through the 90-degree rotation of the pneumatic actuator to drive the rotation of the ball in order to achieve the circulation and blocking media. The direct connection of the actuator to the valve body reduces the chances of failure. Suitable for light industrial machinery small space and narrow space occasions.

PCBN Composites And Inserts

One of the most fascinating materials of our time is polycrystalline cubic boron nitride PCBN - the second hardest material after diamond. At CeramTec, PCBN is used as a cutting material from which indexable inserts are manufactured for machining.
PCBN is produced synthetically and is a "composite material" made of cubic boron nitride and a mostly ceramic binder phase. The ratio of cBN to binder content and the cBN grain size determine the application.
PCBN cutting materials are used in the machining of hard and/or highly abrasive workpiece materials. The high hardness and the extremely high hot hardness (up to temperatures above 1,000°C), the edge stability and inertness towards ferrous materials as well as the basically good chemical resistance give CBN cutting materials a high potential for use in machining. On the cutting material side, a distinction is made between high- and low-cBN cutting material grades.

PCBN (Polycrystalline Cubic Boron Nitride) blanks for cutting tools are composite ultrahard materials sintered by polycrystalline CBN and carbide alloy under ultra-high pressure and high temperature conditions. They combine the hardness, wear resistance, and thermal stability of CBN with the impact resistance and toughness of carbide alloy. PCBN blanks are highly suitable for cutting ferrous and non-ferrous metals with high hardness.
