The DMMOND Polyurethane Slurry Knife Gate Valves: A Class Apart

What sets DMMOND’s Knife Gate Valves apart is their revolutionary design and material use, offering solutions that are both effective and efficient: 

At PARAVALVES, every product is carefully engineered. All the neccesary parameters are studied to develop our solid and reliable knife gate valves.
  • Zero Atmospheric Leakage: Ensuring full tightness even in high pressure and gas applications, these valves are hydrostatically tested to guarantee no leaks, providing a secure and safe operation. 
  • Self-Flushing Design: The valves feature a self-flushing mechanism that prevents solid build-ups, maintaining operational integrity and prolonging service life. 
  • Integral Flange Seals: With a unique sleeve design, the need for flange gaskets is eliminated, ensuring a leak-proof connection to the pipeline. 
  • Replaceable Polyurethane Sleeve: This feature allows for easy on-field maintenance, offering high resistance to abrasive flows and extending the valve’s lifespan. 
  • True Bi-Directional Zero Leak Shut-Off: Designed to handle fluid media in both directions, the valves offer a tight performance for demanding applications. 

Unmatched Versatility and Durability

DMMOND Knife Gate Valves are engineered for a wide range of applications, showcasing their versatility across various industries: 

DMMOND Knife Gate Valves are engineered for a wide range of applications, showcasing their versatility across various industries:
  • Mining and Minerals Processing: In the rigorous world of mining and minerals processing, the demand for valves that can withstand abrasive fluids, high-pressure services, and corrosive environments is paramount. DMMOND Knife Gate Valves excel in this challenging landscape, providing a bubble-tight shut-off and extended service life that is essential for the myriad of critical processes in this industry. From slurry transfer in grinding circuits to handling coal transport, ore processing, and tailings management, these valves are engineered to ensure operational efficiency and reliability. They are also crucial in applications such as pelletizing, sand and silica reduction, dewatering systems, mud washing, acid leaching, and in the complex operations of ball mills, making them indispensable in achieving cost-effective, dependable valve solutions. 
power generation sector is fraught with its own set of challenges, including unplanned downtime, high maintenance costs, and stringent environmental and safety regulations
  • Power Generation: The power generation sector is fraught with its own set of challenges, including unplanned downtime, high maintenance costs, and stringent environmental and safety regulations. DMMOND Knife Gate Valves offer the flexibility and durability needed to maintain plant availability and efficiency. These valves are specifically designed for coal handling, bottom ash management, wet lime scrubbers, and co-generation plants, among others. They play a vital role in dewatering pump isolation, hydrocyclone feed, managing coal combustion residuals, and filter feed tank isolation, ensuring that power generation facilities operate smoothly and compliantly.
