V-port ball valve is a high-performance regulating shut-off valve designed for industrial media containing fibers, sludge and tiny solid particles. Equipped with a V-notched ball core, it delivers powerful shearing capacity to prevent medium winding and blockage, realizing precise flow adjustment and reliable on-off cut-off simultaneously.
We supply two mainstream series: Pneumatic Flanged V-Port Ball Valve (MDP JL600 Series) and Electric Wafer V-Port Ball Valve (MDP JL900 Series).
MDP JL600: Flanged connection, nominal diameter DN25~DN500, matched with MDP JLAT / MDP JLAW pneumatic actuators; available in double acting, single acting normally open and single acting normally closed types.
MDP JL900: Wafer connection, nominal diameter DN25~DN250, fitted with MDP JLA / MDP JLB electric actuators.
Nominal Pressure: 1.0~2.5MPa
Body Material: Carbon Steel WCB, Stainless Steel 304, Stainless Steel 316
Seal Option: PTFE soft seal / Hard alloy metal seal
Working Temperature Range:
W2: -20~150°C | W3: -20~250°C | W4: -29~425°C
Control Mode: Standard on-off type, integral modulating type (4-20mA), RS485 bus type
Optional Accessories: Solenoid valve, filter pressure reducing valve, limit switch, positioner, handwheel mechanism, explosion-proof assembly
V-shaped ball core forms shear cutting effect with the seat, effectively cutting fiber and particle medium, anti-caking and anti-jamming.
No dead-angle internal cavity design, less material accumulation, excellent self-cleaning performance.
Precision machined sealing surface, low leakage rate, stable performance for frequent switching operation.
Wide adjustable ratio, accurate flow regulation, applicable for complex working conditions requiring continuous flow control.
Diversified actuator collocation, support explosion-proof configuration to meet hazardous area standards.
A large paper manufacturing plant previously adopted ordinary globe valves to control pulp flow. Frequent failures severely disrupted production:
Long cellulose fibers inside pulp easily tangled around valve internals. Valves stuck frequently, causing unstable pulp flow, inconsistent paper thickness and unplanned downtime. Frequent maintenance increased spare parts cost and reduced overall production efficiency.
After switching to our pneumatic V-port ball valves for pulp pipeline regulation:
The V-notch ball core generates continuous shear force while rotating, chopping long fibers and preventing winding and blockage. The cavity-free structure avoids pulp sediment buildup. The valve maintains stable, precise flow modulation during continuous operation.
On-site results: Valve jamming faults dropped sharply, maintenance frequency greatly reduced, pulp flow stayed stable, finished paper quality became uniform, and the factory achieved continuous stable production.
Our V-port ball valves are widely adopted in pulp & paper, wastewater treatment, chemical industry, new energy, metallurgy and food processing, ideal for slurry, fiber, viscous and granular medium control.
All valves are packed in export-grade plywood cases to resist collision, damp and rust during ocean transportation. Complete packing list and shipping documents will be provided together. We arrange reliable logistics with loading port at Qingdao Port to ensure safe delivery.
We provide long-term online technical support and spare parts supply after shipment. Custom design is acceptable for special temperature, sealing material and non-standard working conditions.
If you need customized size, special actuator configuration or explosion-proof solution, please send your working condition parameters for professional selection and quotation.
