SODHQ107 top guide piston shut-off valve
The SQDHQ107 type pneumatic diaphragm piston cut-off valve adopts a top guide structure, the valve body structure is tight, the fluid channel is S-streamlined, the pressure drop loss is small, the circulation is large, the valve seat closing performance conforms to GB/T4213-92 standard, and is equipped with a multi-spring diaphragm/piston cut-off mechanism, which has a small structure and large output force. The shut-off valve accepts; the signal from the regulating instrument can cut, open or change the flow direction of the medium to achieve automatic control of process parameters such as pressure, flow, temperature or liquid, and is more suitable for high temperature and high pressure occasions requiring reliability and high closing performance.

SQD207 Corrugated Pipe Seal Lining Fluoride Single-seat Regulating Valve
SQD207 guided pneumatic membrane fluorine lined single-seat wide valve is the executive unit of automatic control instrument, which consists of multi-spring membrane actuator and straight-through single-seat fluorine lined plastic moistening. Because the parts of the valve in contact with the medium are all made of high-pressure injection molding process, lined with corrosion-resistant, aging-resistant polyethylene propylene (F46), and sealed with PTFE bellows, the valve is widely used in chemical, petroleum, metallurgy, medicine, electric power and other industries in the acid (such as hydrochloric acid, sulfuric acid, hydrofluoric acid), alkali and other strong corrosive media and toxic, volatile and other gases and liquid media process control.

SOD104 three-way control valve
SQD104 type pneumatic diaphragm three-way control valve is mainly used to divide a stream of fluid into two streams of outlet fluid or to synthesize a stream of fluid into one stream of outlet fluid. The three-way valve is divided into (SQD104Q) combined regulating valve and (SQD104X) split regulating valve. Valve size, when the pressure difference is small, the valve flow can also be used as a diverter valve, but do not use a diverter valve when the valve size is large and the pressure difference is high.

SOD103 Top Directed Double Seat Regulating Valve
SQD103 top-guided double-seat regulating valve adopts double-guided structure, the valve body structure is tight and light, the fluid channel is S-streamlined, the pressure drop loss is small, the circulation volume is large, the adjustable range is wide, and the flow characteristic accuracy is high. Due to the guidance at the top and bottom of the spool, it has the characteristics of anti-micro wear resistance. The regulating valve is equipped with a multi-spring film actuator, which has a small structure and a large output force. It is more suitable for good stability, high reliability, high pressure, high pressure difference and good control under the process conditions where the slurry is easy to block in the fluid medium.
