Product Introduction
Pulp Valve includes two core series: Pneumatic Diaphragm Control Valve and Manual Knife Gate Valve, core pipeline accessories for flow regulation and on-off in complete pulping, coating and white water recovery lines. Suitable for pulp, calcium carbonate coating, water-based plastic-free coating, fiber white water sewage and steam pipelines. It realizes automatic flow adjustment, pipeline shut-off and sludge interception, featuring anti-clog, wear & corrosion resistance and zero leakage, compatible with full-line equipment including paper machines, drying cylinders, pressure screens, DAF and microfiltration machines.
Machine Structure & Configuration
Two valve series fully cover automatic flow regulation and pipeline cut-off & drainage demands, compatible with all media of pulping, coating, extrusion lamination and wastewater recovery lines;
01
Wear-resistant stainless steel / hard alloy internal trim prevents pulp blockage and internal leakage under long-term fiber & filler medium conveying, cutting maintenance downtime;
02
Anti-corrosion coating & corrosion-resistant internal parts resist acid-alkali papermaking medium and high-temperature steam erosion for long service life;
03
Full nominal diameter non-standard customization, bulk complete-set supply for whole paper machine projects, supporting central control automatic linkage renovation;
04
Stable sealing for 24-hour continuous papermaking operation, drastically reducing waste of pulp, steam energy loss and sewage leakage loss.
05
Core Advantages
Pneumatic control valve supports DCS central automatic flow regulation, built-in heat sink adapts dryer high-temperature steam, hard alloy trim resists coating & fiber erosion for stable flow adjustment to guarantee accurate coating dosage and drying temperature control;
Knife gate valve features straight-through dead-space-free channel to avoid pulp blockage, bidirectional zero-leakage seal with compact size for easy installation, ideal for fast cut-off & drainage of sewage, sludge and coarse pulp pipelines;
Full series resists acid-alkali, filler and high-temperature papermaking medium corrosion, wear-resistant internal trim prevents internal leakage & valve jamming under long-term operation to cut production downtime maintenance;
Complete nominal diameter range, two valve types matched in one solution to cover all pipeline demands of pulp conveying, steam temperature control and sewage drainage;
Compatible with intelligent workshop renovation: control valves link central control system, gate valves can be fitted with pneumatic/electric actuators for remote on-off operation;
Strict hydraulic sealing test before delivery with zero leakage standard, reducing pulp & steam waste and lowering comprehensive papermaking production cost.

FAQ
Q: What's the difference between control valve and knife gate valve for paper mill?
A: Control valve automatically adjusts medium flow for steam & coating quantitative control; knife gate valve cuts off pipeline for pulp, sludge and sewage drainage on-off.
Q: Can the pneumatic control valve work under dryer high-temperature steam?
A: Equipped with extended heat sink structure to isolate high temperature, specially designed for saturated steam of drying cylinders.
Q: Will knife gate valve get blocked by fiber pulp easily?
A: Straight-through flat blade channel without cavity, no pulp accumulation or hanging, anti-blockage for high-fiber pulp.
Q: Can the valve connect with paper machine DCS central control system?
A: Pneumatic control valve with 4–20mA positioner supports DCS linkage; knife gate valve can add electric/pneumatic actuator for remote control.
