Product Details

Electric proportional control valveThe nominal diameter ranges from 20 to 200mm, with nominal pressures of 1.0, 1.6, 4.0, and 6.4MPa. The operating temperature range is from -40 ℃ to 450 ℃, and the received signal is 0~10mA.DC or 4~20mA.DC. The electric single seat regulating valve is suitable for situations with small pressure difference, high medium viscosity, or slight particle impurities. Electric sleeve regulating valve is suitable for situations with large pressure difference. According to the material of the sealing part of the valve, there are two types of seals: metal metal and non-metal metal seals. According to the different packing materials, it can be divided into two types: general packing seal and corrugated pipe seal. The former is used in general occasions, while the latter is used in important occasions where leakage is not allowed. The flow characteristics are linear or equal percentage.Electric proportional control valveThere are two types of actuators available: ordinary and electronic.

Product Name	ZSFB electric explosion-proof single seat (socket) regulating valve
Product Model	ZSFB
Nominal Diameter	DN20-DN300mm
pressure range	1.6-6.4MPa
Valve body material	Cast steel, stainless steel

Product Overview:

ZSFB electric explosion-proof single seat (sleeve) regulating valve, composed of low flow resistance straight through single seat valve, or low flow resistance sleeve valve matched with PS or 3810 series electric explosion-proof actuator, etc. The electric actuator has a servo amplifier inside, which does not require a separate servo amplifier. It has input control signals (4-20mADC or 1-5VDC) and a single-phase power supply to control operation, enabling adjustment of parameters such as pressure, flow rate, temperature, and liquid level. This valve has the characteristics of small volume, light weight, simple connection, high flow rate, and high adjustment accuracy. It is applied in industrial process automatic control systems in industries such as power, petroleum, chemical, metallurgy, light industry, teaching and research equipment.
