By using the Y Type Bellows Seal Globe Valve configuration of the valve, it is feasible to prevent the pressure drop that is often seen when employing globe valves. The seat and stem of the Y-type globe valve are angled at an angle of about 45 degrees with regard to the axis of the pipe when the valve is configured in this manner. Because of the angle, the stem, the bonnet, and the packing are all exposed to pressures that are rather high.
- It has a long cycle life that is assured to be achieved.
- BELLOWS are designed for and tested to work well in environments with high levels of pressure and temperature.
- The fact that the stem itself does not spin, the presence of thrust bearings inside the stem nut, and the central grease fitting that is used for lubricating the stem nut are all factors that contribute to the LOW TORQUE.
- The backseat and the stem packing each count as one of the tertiary stem seals.
- Continuous normal functioning both during and after the fire test is required of safe valves designed to extinguish fires.
- On-the-fly maintenance is made easy with valve stem-bellows assemblies that include a bonnet because it is quick and easy to remove and replace.
- When it comes to cutting through the seal weld, there is specialized power equipment that was created specifically for the task at hand.
