Core features of the product
The VPFL series regulating valve has multiple advantages in structural design and performance, and can flexibly adapt to the needs of different scenarios. The specific characteristics are as follows:
In terms of structural design, a tilted valve seat design is adopted, with good flow coefficient performance. Coupled with an integrated compact mechanism, the overall volume is small and the installation process is convenient, which can effectively save installation space. In terms of material selection, a stainless steel structure that can adapt to corrosive environments is adopted, which can flexibly respond to various application scenarios, especially suitable for working environments such as chemical industry where corrosive media are transported.
In terms of performance stability, the components used in this series of regulating valves have strong durability and are equipped with self-lubricating valve stem double guides, which can ensure the reliability of the valve during operation. After a large number of working cycles, no additional maintenance is required, which can effectively reduce the maintenance cost of the equipment. In terms of adaptability, multiple sealing materials are used, which can be flexibly selected according to different application environments; Paired with servo controllers of different specifications, it can achieve high differential pressure liquid interception operation and large stroke control, adapting to the needs of various working conditions.

Product application scenarios
The application scenarios of VPFL series regulating valves are relatively wide, mainly suitable for various equipment such as water cooling devices and dyeing machines. Among them, water cooling devices have become a commonly used supporting equipment in modern bar production lines, and their specific application configurations are as follows:
In the configuration of the water cooling device, the main valve is the burner valve VPFL series DN40, which is available in stock and can be quickly put into use; The accompanying pneumatic installation kit includes components such as solenoid valves, flow regulators, installation brackets, and pneumatic triplets, which can be directly installed and used to simplify the overall installation process and improve installation efficiency.
Detailed product parameters
1、 Basic parameters
The closing mode of VPFL series regulating valves includes three types: NC normally closed, NO normally open, and DE double acting. Customers can flexibly choose according to their actual usage needs; The size range covers DN 15 to DN 200, covering various caliber requirements, with DN40 specification available in stock; The pressure level is PN 16; The working temperature range is -30 ℃ to+200 ℃, and the specific temperature adaptation range is determined by the type of valve and sealing ring.
2、 Material parameters
The valve body material is made of ISI316 stainless steel, with DN 15 to DN 100 specifications made of micro cast wax, and DN 125 to DN 200 specifications made of forged and electrically bonded plates; The valve seat and upper valve cover are both made of AISI316 stainless steel to ensure the corrosion resistance and durability of the components.
The valve plug is made of AISI316 material and has a linear action when quickly opened. It is divided into two types: one with PTFE-PTFE/CG plug and the other with silicon/EPDM/fluororubber plug; The packing box is equipped with standard PTFE rings and viton rings. The DN 15/DN 50 (NPFL) specification uses PTFE rings, while the DN 15/DN 50 (NPFL) high-temperature scenario uses PTFE rings and graphite, which can adapt to a high temperature environment of 200 ℃.
The material of the servo controller is AISI304 forged steel, and the valve stem is made of AISI316L rolled steel, equipped with dual guides; The sealing ring material includes NBR and fluororubber, which can be flexibly selected according to the usage scenario.
3、 Connection method
This series of regulating valves supports two connection methods, namely reducing flange connection and welding connection. The reducing flange connection can adapt to three pressure levels of PN 6, PN 10, and PN 16, and the flange material is AISI304/316; At the same time, other types of terminal connection methods can be provided according to specific customer requirements.
4、 Servo controller parameters
The starting mode of the servo controller has a minimum pressure of 4 bar and a pressure of 8 bar; The cylinder specifications include multiple options such as φ 63, φ 82, φ 118, φ 136, φ 153, and φ 235; The current equipment adopts a locator (NC type), and the supporting accessories include a handwheel, magnetic sensor, proximity sensor, micro switch box, solenoid valve, stroke regulator, flow gate, etc.
According to actual usage needs, a double acting large stroke servo controller can be provided; If soft materials are inserted, it can adapt to a 20% increase in differential pressure, further improving the adaptability of the equipment.
5、 Other parameters
Under single action mode, the gas consumption at a pressure of 6 bar can be queried for specific values based on actual operating conditions to ensure accurate matching of parameters with usage scenarios.
The burocco VPFL series stainless steel regulating valve relies on stable operating performance, flexible adaptability, and diverse specification selection, and is widely used in multiple industrial fields such as chemical engineering and bar production. Among them, DN40 specification is available in stock, which can achieve fast delivery and meet customers' urgent usage needs; The overall structural design of the product is reasonable, with strong durability. The accessory configuration of * can provide reliable support for fluid regulation operations in various industrial productions, meeting the requirements of the chemical industry for equipment corrosion resistance and operational accuracy.
