The stop valve is also known as a globe valve or linear motion valve. It is commonly used to stop, start and regulate flow. The disk of the globe valve has been subjected to heat treatment. The seat of the valve is butt-welded with cemented carbide, which helps to extend the lifespan of the quality valve. This valve can be used manually, or used in combination with an actuator. The entire process is numerically controlled, and the product can withstand high temperature of up to 300℃. Notable features of the spherical-disc valve include: a nice exterior, excellent structure, zero leakage, and a long service life. &nb
