  • Product introduction

Operating principle

1. When the handwheel turns clockwise, the valve stem moves downward, and the disc drops to make the sealing surface close and cut off the access. When it is reversed, the valve stem opens and seals at the lifting point.

2. An upper seal is added to the valve. When the valve is open, it seals with two layers of packing and protects the packing to a certain extent

3, this valve USES nylon products as the sealing surface, the packing is soft forming packing, the upper seal is also soft material, the sealing performance is good.

The valve body structure has the straight through type, the straight flow type and the right Angle type.The straight through is a common structure, but its fluid resistance.Direct flow fluid resistance is small, mostly used to contain solid particles or viscosity of the fluid.Rectangular valve body is mostly forged, suitable for smaller through, higher pressure globe valve.

advantages

1. Simple structure, convenient manufacturing and maintenance.

2. Small working schedule and short opening and closing time.

3, good sealing, small friction between sealing surface, long life.

The disadvantages are as follows:

1, the fluid resistance, open and close when the force required.

2. It is not suitable for medium with particles, high viscosity and easy to coking.

3. Good adjustment performance.

Globe valve type according to the position of stem thread can be divided into male thread type, female thread type.According to the direction of the medium, there are straight, straight and Angle type.Globe valves are divided into sealing type, packing sealing globe valve and bellows sealing globe valve.

When the globe valve is opened, the opening height of the disc is 25% ~ 30% of the nominal diameter, and the flow rate has reached, indicating that the valve has reached the fully open position.So the full open position of the globe valve should be determined by the stroke of the disc.

Valves of this class shall generally be installed horizontally in piping.
