A two piece of ball valve is typically a quarter-turn valve with a perforated ball in the middle to control flow. These valves are known for being durable with excellent shutoff, but don’t always offer very precise control. Let’s talk about when it’s okay to use a ball valve as a control valve.
Even though two piece of ball valve aren’t the best device to control flow, they are still commonly used because of their cost effectiveness. You can get away with using a ball valve in an application that doesn’t require precise adjustability and control. For example, a ball valve should have no problem keeping a large tank filled at a certain level within a few inches.
As with any equipment, you will need to take the complete process conditions into consideration before selecting your valve. This includes the product or material, size of piping, flow... less
Sheet Metal Parts are formed by presses and molds to apply external force to plates, strips, pipes, and profiles to plastically deform or separate them to obtain workpieces (sheet metal parts) of the desired shape and size.

When natural rubber is plasticized with an open mill, the roller temperature is 30-40 ° C, and the time is about 15-20min. When using an internal mixer to plasticize, the time is about 3-5min.
The Mooney viscosity of styrene-butadiene rubber is mostly between 35-60. Therefore, styrene-butadiene rubber can be used without plasticizing, but the dispersion of the compounding machine can be improved after plasticizing.
Butadiene rubber has cold flow and lacks plasticizing effect. The Mooney viscosity of butadiene rubber is relatively low, so it does not need to be plasticized.
Neoprene has a large plasticity, and can be thinned 3-5 times before plasticizing, and the thinning temperature is 30-40 ° C.
The molecular main chain of ethylene-propylene rubber is a saturated structure, and it is difficult for plasticization to cause molecular cracking. Therefore, it is necessary to choose a variety with low Mooney viscosity instead of plasticization.
Nitrile rubber has... less
