Our engineering team can provide tailored designs to meet specific project requirements.Applications The blade-shaped gate at the bottom provides exceptional cutting force, making it ideal for media containing fibers and suspended particles. Consequently, this product is widely used in1.Paper manufacturing2.Wastewater treatment3. Mining Sugar production4.Synthetic fiber industries Design Features 1.Built-In Packing Chamber Utilizes rubber packing for enhanced sealing reliability. A self-locking nut prevents loosening during prolonged operation.2.Point-Type Guide Block The gate is guided by nylon point-type blocks, ensuring stable movement. A smooth transition at the port base minimizes residue buildup and reduces operational failures.3.Blade-Arc Gate The blade-shaped arc design at the gate base delivers superior cutting performance, particularly for pulp and fiber-rich media. After precision grinding, the gate undergoes hard chrome plating for exceptional wear resistance and corrosion resistance.4. Movable Seal Seat Features a spring-loaded O-ring to maintain preload force, ensuring tight contact between the seat and gate. Automatic compensation for wear during long-term use extends service life. Options include metal seats, PTFE, or EPDM seats to suit diverse operating conditions.5. Multi-Flow Port Configurations Sealing ports can be designed as V-shaped, triangular, or pentagonal to meet varying flow regulation requirements.After Sales ServiceStandard Warranty: 12 months Global Support: 24/7 technical assistance and spare parts supply.Training: On-site or remote operation/maintenance training.Company ProfileShandong Huawo Fluid Equipment Co., LtdYour Trusted Partner in Precision Fluid Control Solutions.
