Material Selection for Electric Blind Plate Valves

People pick materials and sizes for electric blind plate valves. These choices change the valve’s service life, sealing effect and working condition.

Workers need to check four things before choosing. The four things are pipe fluid, working pressure, temperature and control needs.

Good choices prevent two common problems. The two problems are valve damage and fluid leakage. These problems come from wrong materials or mismatched sizes.

Right choices keep the whole pipe system running well.

People focus on two points when they select materials. The two points are pipe fluid features and working surroundings.

Workers pick body and blind plate materials based on three factors. The three factors are fluid corrosion, working temperature and working pressure.

Carbon steel fits common neutral fluid. It works at normal temperature and normal pressure. Its overall performance is good.

Stainless steel fights corrosion well. People use it for strong acid, alkali and chemical fluid.

High-strength alloy stands high temperature and high pressure. It works under harsh working conditions.

Sealing parts need to match the pipe fluid. This match stops parts from breaking due to corrosion.

Flexible graphite and PTFE fit most kinds of fluid. Workers can pick either one based on real working sites.

Workers choose matched motors and electric parts for electric actuators. They make the choice according to ambient temperature. This step reduces machine faults in hot places.

Size selection needs to follow pipe data.

First, workers match the valve’s inner width to the pipe’s width. This way fluid flows without slowdown.

Second, workers choose valves with matching pressure grades. The grades fit the fluid pressure inside pipes.

Third, workers pick two types of electric motors as needed. The two types are switch type and adjustable type.

Workers also pick connection ways such as flange and welding. These ways make on-site installation simple.

The right connections let the machine run steadily during adjustment.
