Bevel valve introduction

The Bevel valve can dissipate energy by the friction between water and air and the vortex in the water after it enters the water. When several conical valves are arranged in parallel, the distance between the axes should not be too small (for example, not less than 5 times the diameter of the valve shell D), otherwise the flow will collide with each other, resulting in a reflected flow. If the flow falls into the valve chamber, it will be difficult to operate. After improving the cone Angle of 50 °, and compared with 90 ° taper Angle valve, can make the distance between valve and valve for D (2.75 ~ 3.0), water tongue area is by two-thirds.

Proportional Solenoid

Proportional Solenoid - Included in this category of solenoids are the uniquely designed magnetic circuits that effect analog positioning of the solenoid plunger or armature as a function of coil current. These solenoids, whether axial or rotary, employ a flux carrying geometry that both produces a high starting force (torque), and has a section that quickly begins to saturate magnetically. The resulting force (torque) profile as the solenoid progresses through its operational stroke is nearly flat or descends from a high to a lower value. The solenoid can be useful for positioning, stopping mid-stroke, or for low velocity actuation; especially in a closed loop control system. A uni-directional solenoid would actuate against an opposing force or a  dual solenoids  system would be self cycling.

A brief introduction of explosion proof coil

1. Introduction of foreign advanced technology, use flame retardant casting materials to encapsulate the electrical components in the enclosure 2. Internal fuse tube, pressure sensitive resistance and other elements can enhance the explosion proof performance and work stably and reliably 3. The cover adopts zinc alloy material to withstand the impact force of more than 20J 4. The  explosion proof coil  has a wide application surface, and the static iron core seat and high-energy energy can be matched with the coil to assemble the explosion-proof electromagnetic valve Explosion proof coil  can be equipped with two - way, two - way, two - way, two - five - way, three - five - way and other series of explosion-proof electromagnetic valves.
