Electric V type regulating ball valve ZAJV-16C


Fouten Flow Control (Jiangsu) Co., Ltd. specializes in producing electric V type regulating ball valve ZAJV-16C, which is composed of angular stroke electric actuator and V type open ball core valve body. It is suitable for flow and pressure regulation control of fiber, particle or suspended medium in industries such as papermaking, chemical, petroleum, metallurgy, etc.
Structural form
The valve body is connected by an integral flange, and the ball core has a V type notch. It rotates relative to the valve seat to generate shear force, which can cut off fibers or solid particles and prevent them from getting stuck. The valve core and valve seat adopt a leaf spring loaded movable valve seat structure, which is reliable in sealing and has a long service life. The actuator is an angular stroke electric device with high output torque and control accuracy. It can be equipped with 4-20mA adjustment module to achieve proportional control.
Main material
Valve body: cast steel WCB, stainless steel CF8/CF8M; Core: Stainless steel 304/316, surface can be plated with hard chromium or spray welded with hard alloy; Valve seat: PTFE soft seal or 304 welded hard alloy metal seal; Valve stem: stainless steel 2Cr13/304/316; Packing: PTFE or flexible graphite; Execution mechanism: Aluminum alloy or steel shell, built-in servo control module.
Sealing and Drive
The sealing form can be PTFE soft seal or metal hard seal, and the leakage level of soft seal can reach ANSI/FCI 70-2 Class VI, Hard sealing is suitable for high temperature and high pressure working conditions. The driving method is an electric actuator, with optional power supply AC220V/380V and input signals 4-20mA or 1-5VDC. No additional servo amplifier is required, and automatic adjustment of pressure, flow rate, temperature, and liquid level can be achieved.
Technical parameters
Nominal caliber: DN25 to DN400; Nominal pressure: PN1.6~PN6.4MPa; Applicable temperature: - 29℃~200℃ (soft seal)/- 29℃~450℃ (hard seal); Applicable media: pulp, mud, fibrous liquids, granular media, and generally corrosive fluids; Traffic characteristics: approximately equal percentage; Adjustable ratio: 300:1; Connection method: flange FF/RF; Design standards: GB/T, 12237, API, 608.
Applicable Industries
Widely used in industries such as papermaking, pulp making, sugar production, petrochemicals, coal chemicals, metallurgy, sewage treatment, food fermentation, etc., the industrial process automatic control system is particularly suitable for regulating working conditions where the medium contains fibers, small solid particles, or suspended solids. It can replace imported V ball valve products.
Product Advantages
1. V type notched ball core has strong cutting ability and is not easily blocked; 2. has percentage flow characteristics, wide adjustment range, and high control accuracy; 3. leaf spring loaded valve seat, reliable sealing, long service life; 4. electric drive, intelligent control, can be remotely operated; 5. has a compact structure, light weight, and easy installation and maintenance; 6. actuator can be selected from explosion-proof and adjustable types, with complete accessories.
Execution mechanism configuration
Standard configuration intelligent electric actuator, output torque 50N · m~2000N · m, with overload protection, manual operation, position feedback, fault self diagnosis and other functions. Optional adjustable modules, on-site handwheels, explosion-proof enclosures, heating devices, etc., to meet different working conditions and control requirements. Action time 8~60 seconds (depending on caliber and torque).
Selection Instructions
Please provide information such as nominal diameter, working pressure, medium name and temperature, connection standard, driving method (electric switch type/regulating type), power specifications, whether explosion-proof is required, and material requirements for valve body and sealing surface when placing an order. It is recommended to use a hard sealed structure for media containing fibers or particles; It is recommended to use metal sealed valve seats for high-temperature media.
Installation and maintenance
Ensure that the pipeline flange is coaxial with the valve body flange during installation, and tighten the bolts symmetrically to avoid uneven stress that may cause deformation of the sealing surface. The wiring of electric actuators should comply with electrical specifications and be reliably grounded. Before putting into use, conduct a no-load test run to check whether the switch action, limit setting, and signal feedback are normal. Regularly check the sealing of the valve seat and the lubrication condition of the actuator.

Common problems in product selection
Can ZAJV-16C replace ordinary ball valves for continuous flow regulation?
It is necessary to calculate the flow coefficient based on the minimum, normal, and maximum flow rates and corresponding pressure differentials, and confirm that the V flow channel, valve seat, flow characteristics, and actuator are suitable for adjustment. Simply replacing the actuator of the switch ball valve with a regulating type cannot be considered equivalent in performance.
Do I need to confirm the input signal and valve position feedback when connecting ZAJV-16C to DCS?
It is necessary to confirm the control input, valve position feedback, power or gas source conditions, interfaces, and fault location separately. Input and feedback are not the same function, and it cannot be assumed that all analog signals or communication protocols are fully equipped based solely on the name "regulating type".
Will ZAJV-16C automatically shut down after a power outage?
The power-off action cannot be determined solely by the name of the electric drive. Ordinary electric actuator cannot default to having automatic valve closing function when power is lost; If the process requires fault closure, the energy storage or other fault safety scheme of the actuator should be confirmed at the time of ordering, and the entire valve interlock verification should be completed.
