Explore our precision-engineered valve products optimized for automated pneumatic process systems across water treatment, chemical, energy, and industrial sectors.




A sluice valve — also widely referred to as a gate valve — is a linear-motion valve that controls fluid flow by raising or lowering a flat gate (or wedge) across the flow path. When fully open, the gate is retracted entirely, allowing unobstructed, full-bore flow with minimal pressure drop. When closed, it provides a tight, bidirectional shutoff suited for isolation duties in high-demand industrial pipelines.
In the context of automated pneumatic process systems, sluice valves are actuated by pneumatic actuators — devices that convert compressed air energy into mechanical movement. This combination creates a powerful, fast-response, and energy-efficient valve assembly that integrates seamlessly into modern PLC (Programmable Logic Controller) and SCADA (Supervisory Control and Data Acquisition) environments.
Unlike manual gate valves, pneumatically automated sluice valves eliminate human intervention, reduce operational errors, and enable remote monitoring — a critical requirement in Industry 4.0 smart factory environments. Their robust construction from ductile iron, cast iron, or stainless steel ensures longevity under high-pressure, high-temperature, and chemically aggressive conditions.
The demand for automated sluice valves in pneumatic process systems is accelerating worldwide, driven by industrial digitalization and infrastructure investment.
The global industrial valve market was valued at over USD 80 billion in 2023 and is projected to exceed USD 120 billion by 2030, with pneumatically actuated gate and sluice valves representing one of the fastest-growing segments. Key growth drivers include:
China remains the world's largest manufacturer and exporter of industrial valves, with companies like KR VALVE (TIANJIN) Co., LTD supplying pneumatic sluice valve solutions to over 50 countries across Europe, Asia, Africa, and Oceania. The competitive advantage lies in combining ISO-certified manufacturing quality with cost-effective production and rapid customization capabilities.
Engineered for precision, durability, and seamless integration into automated control architectures.
The fully retracted gate provides zero flow restriction when open, minimizing pressure drop across the valve — critical for high-volume pipeline systems requiring energy-efficient fluid transport.
Compressed-air actuators deliver sub-2-second response times for open/close cycles, enabling rapid process adjustment and emergency shutoff in automated pneumatic control loops.
Precision-machined wedge gates and resilient or metal seats ensure bubble-tight shutoff in both flow directions, meeting ANSI Class IV and Class VI leakage standards.
Available in ductile iron (GGG40/GGG50), cast iron, carbon steel, and stainless steel (SS304/SS316) to withstand aggressive media including seawater, chlorinated water, and chemical slurries.
Compatible with electro-pneumatic positioners, limit switches, and solenoid valves for full integration with PLC, DCS, and SCADA systems — enabling real-time position feedback and remote diagnostics.
Stem sealing with O-rings and PTFE packing, along with self-adjusting gland designs, ensure long service intervals and minimal maintenance downtime in continuous process environments.
Industry 4.0 is reshaping how sluice valves are designed, deployed, and managed in pneumatic process systems.
Embedded sensors and AI algorithms now monitor valve actuator torque, seat wear, and stem friction in real time, predicting failures before they occur and scheduling maintenance proactively — reducing unplanned downtime by up to 40%.
Modern pneumatic sluice valve assemblies are increasingly equipped with IO-Link or HART communication protocols, enabling integration into Industrial IoT platforms and digital twin simulations for process optimization and remote commissioning.
Next-generation valve islands with integrated pressure regulators and exhaust air recycling systems reduce compressed air consumption by 20–35%, aligning with global carbon neutrality targets and reducing operational energy costs.
Hybrid actuators combining electric and pneumatic power sources are emerging for safety-critical applications, providing pneumatic speed with electric precision — ideal for partial-stroke testing in safety instrumented systems (SIS).
Pre-assembled pneumatic valve skids with integrated sluice valves, actuators, positioners, and instrumentation are reducing on-site installation time by up to 60%, particularly in offshore and remote process plant applications.
PTFE-encapsulated and graphite composite seals for sluice valve stems and gates are extending service life in high-temperature steam and aggressive chemical service beyond 15 years, reducing total cost of ownership significantly.
Pneumatic sluice valves serve as critical control components across a wide spectrum of industrial and municipal process systems.
Pneumatically automated sluice valves control flow in water intake, filtration, and distribution mains. Their full-bore design prevents sediment accumulation, and automated cycling enables scheduled flushing operations without manual intervention — essential for large-scale WTP automation.
Heavy-duty sluice valves with pneumatic actuators manage penstock isolation, turbine bypass, and emergency shutoff in hydropower stations. Their robust construction handles DN200–DN3000 diameters and pressures up to PN25, meeting the demands of large-scale dam construction projects.
In chemical reactors and pipeline networks, pneumatic sluice valves with stainless steel or alloy bodies isolate aggressive media — acids, alkalis, solvents — with zero leakage. Integration with SIS ensures automatic shutoff on process upset conditions, protecting personnel and equipment.
Automated sluice valves regulate hot water and steam flow in district heating networks and power plant auxiliary systems. High-temperature resilient seats and extended stem packing maintain sealing integrity at temperatures exceeding 180°C, ensuring reliable year-round operation.
In large commercial and industrial buildings, pneumatic sluice valves are integrated into HVAC chilled water loops and fire suppression systems. Their fast-acting pneumatic actuators enable zone isolation within seconds during fire events, meeting NFPA and EN standards for life safety systems.
Seawater desalination plants and offshore oil & gas platforms require valves with extreme corrosion resistance. Duplex stainless steel and super duplex sluice valves with pneumatic actuators handle high-chloride environments, meeting NACE MR0175 standards for sour service applications.
