ZMJBP-16F46P pneumatic thin film lined PTFE single seat regulating valveDetailed product description：

The ZMJBP-16F46P pneumatic thin film lined PTFE single seat regulating valve is the execution unit in the automatic control instrument. It consists of two parts: a pneumatic thin film actuator and a straight through single seat fluorine lined plastic valve. Due to the high-pressure injection molding process used in the parts of the valve that come into contact with the medium, lined with corrosion-resistant and aging resistant polytetrafluoroethylene (F46), and sealed with polytetrafluoroethylene bellows, this valve is widely used for process control of acid, alkali, strong corrosive media, toxic, volatile gas, liquid media, and other industries such as chemical, petroleum, metallurgy, medicine, and power.

1、 Product Features
1. Corrosion resistance: The valve body cavity, valve core, valve seat, and valve stem are all made of 316 stainless steel, which can resist acid, alkali, and strong corrosion.
2. Good sealing performance: The corrugated pipe and packing made of polytetrafluoroethylene material are double sealed to ensure no leakage.
3. Small leakage: Due to the soft sealing of the valve core and seat, the leakage is lower than the national IV level standard.
4. Adopting a lightweight and compact multi spring actuator, with small volume, light weight, and high adjustment accuracy.

2、 Part material
Valve body and cover: HT200, ZG230-450, ZG1Cr18Ni9Ti
Valve core and seat: 1Cr18Ni9Ti, welded with Stellite alloy
Soft seal valve core: reinforced polytetrafluoroethylene
Bellows: 1Cr18Ni9Ti PTFE Bellows
Filler: Rubber asbestos board, 10 '', 1Cr18Ni9Ti asbestos wrapped gasket
Membrane cover: A3
Ripple film: Nitrile rubber clip reinforced polyester fabric
Spring: 30SIMN
Valve stem and push rod: 2Cr13, 1Cr18Ni9Ti
Lining: 2Cr13

Allowable pressure difference of regulating valve: (see Table 3)
The output force of the pneumatic diaphragm actuator of the standard pneumatic single seat valve is constant. To achieve ideal regulation and closure, the pressure difference of the valve must be limited to a certain value, and this product should be selected according to Table 3. When the pressure difference exceeds the allowable value, the spring preload can be adjusted, and a valve positioner or other actuator can be used to overcome the unbalanced force. However, when placing an order, it is necessary to contact our company and explain the specific situation before placing the order.
