High Performance Sealing Electric Welded Ball Valve For Precise Control

Product Specification

Highlight:  Electric Welded Ball Valve

Product introduction:

An electric ball valve is an automated control valve driven by an electric motor. It achieves flow control, pipeline cutoff, and

flow rate regulation for liquids and gases by precisely adjusting the rotation angle of the ball. It supports intelligent control

methods such as remote control systems and PLC (Programmable Logic Controller), enabling remote operation beyond

spatial limitations and seamless integration into industrial automation processes, which greatly enhances control efficiency

and accuracy. Due to its characteristics of convenient operation, rapid response, and precise control, it is widely used in

industries such as industrial manufacturing, petrochemicals, water treatment, and thermal power generation, playing a key

role in ensuring stable system operation and improving production efficiency.

Product technical parameters:

Product features:

1. The body uses the all welded structure, there won't be the phenomenon such as external leakage, the valve structure is more compact, easy instalation.

2.  Low operating torque: valve adopts the self-lubricating backing PTFE metal collar, small friction torque, to ensure that the valve to operate under the condition of the low torque.

3. Double block and excretion function (DBB): both sides ofthe valve in the cloed position and the ballunder pressure at the same time, the bodylumenofmedium (gas or liquid) from the drain valve discharge.

4. Double piston efect seat structure design: both sides ofthe seat underthe action of pressure seal(double piston effect,. Double sealing seat desigrfeatures: once the upstream seat is damaged and leaking, medium pressure on the downstream side intothe valve cavity, the seat into the sphere closcontact,can sealthe downstream seat.

5.Reliable seating: structure of floating seat, the seat can be freely floated along the centerine of the valve. For two-way valve seal, under the conditionof low pressure, initial seal were obtained through the seat after the spring load. With the increase of pipeline pressure, supplemented by spring forceafter the seat ring, to keep close contact with the ballseat,reliable sealing effect. Seat sealing adopts combined sealing structure, primary seaing caneffectively prevent solid particles of the sealing surface is damaged,the secondary sealis rubber ring seal, can quarantee to achieve "zero"leak valvesealing requirements. According to the operation condition, the seat can be embedded in polymer engineering plastic seals.

6. The emergency seat sealing system:valve seat desian a emergency sealing system, When there was a trace leak sof sealing surface is damaged, biniection system,auxiliary seal when the pipelinewith pressure to the valve sealing surface injecting sealant, a temporary auxiliary seal. When thetransmission medium contains a smal amount of solid articles, o protecthe sealina surace or reduce operaina toraue,cleaners or lubricant can biniected by the iniection system,the sealing surface to make the necessary cleaning and lubncating treatment. in a check valve on the valve at the bottomof the design at the same time, ensure the media does not leak from the position.
