ZHF(H) three-way shunt confluence regulating valve is a kind of industrial control valve, widely used in automatic control system, used to adjust the flow, pressure, temperature and other process parameters of pipeline media. The following is a detailed description of the regulating valve:

Overview:

ZHF(H) three-way regulating valve has two modes of action: three-way combined flow and three-way shunt, which can replace two two-way valves and a three-way valve nozzle, and is widely used in the field of industrial control.
Structural features:

Spool structure adopts cylindrical thin-wall window, side oriented, with good stability, not easy to produce vibration and low noise characteristics, allowing the use of large pressure difference, simple connection.
Standard specifications:

Nominal diameters range from DN20 to DN300, nominal pressures from PN16 to PN100, CLASS 150LB to 600LB, connection methods include flanges and welds, valve covers are available in various forms, and packing and gaspacking materials are available.
Type compilation:

The model is composed of the actuator, structural form, nominal pressure, body material and nominal diameter, such as: pneumatic film three-way shunt regulating valve, heat dissipation type, pressure PN16, body material is WCB, nominal diameter DN50, model is: ZJHHFG-16C DN50.
Performance index:

Flow characteristics include straight line and equal percentage, adjustable range of 30:1, rated CV value from 8.5 to 1280, hard seal allowable leakage level IV (0.01% valve rated capacity), performance indicators include basic error, return error, dead zone and always point deviation.
Select parameter table:

Detailed mapping of the seat diameter to the rated flow coefficient CV is provided, along with travel and optional flow coefficient Cv for different nominal diameters.
Installation precautions:

Before installation, read the manual, carried out by professional and technical personnel, water flow direction should be consistent with the arrow of the valve body, maintain maintenance space, power debugging after installation, and carry out no water and water test.
Fault analysis and maintenance:

During maintenance, it is necessary to focus on checking the inner wall of the valve body, the valve seat, the spool and the sealing filler. Daily maintenance includes regularly adding lubricating oil, checking the air source and maintaining hygiene.
Electric three-way regulating valve features:

The electric three-way regulating valve is composed of an electric actuator and a three-way regulating valve body. It has the characteristics of sensitive action, simple connection, large flow, small volume and high adjustment accuracy, and the control accuracy and performance are significantly improved than the traditional models.
This information provides a comprehensive overview of the ZHF(H) three-way shunt and combination regulator, including its construction, performance, installation and maintenance essentials.
