FREE-VALVEâ??s slurry valves are idea for bi-directional tight on-off service in abrasive slurry applications,the valve adopts the full-lined wear-resistant polyurethane injecting with the whole mold, and all media passing areas are wrapped in the polyurethane lined to achieve all-round wear-resistant protection,which provides excellent wear life with 100% positive shutoff of abrasive slurry,the Valves are designed for applications in mining.
Features
1.Bi-directional flow,zero Leakage and shut-off, allowing valves to be installed in either direction.
2.The polyurethane lined has integral flange seals, eliminating flange gaskets when installing.
3.Resilient seats can be easily replaced after removing valve from the line.
4.Full round port allows for high flow capacity with minimum pressure drop.
5.Valve plate use wear - resistant stainless steel plate with various types of wear - resistant surface treatment.
6.Wafer type can also be made if necessary

Applications
FREE-VALVEâ??s slurry knife gate valve is designed and equipped to handle tough and abrasive shut off applications involving slurries, powders or granular substances as well as pulp stock, paper and recycled paper.Mining and minerals processing,Pulp and paper applications,Water & waste water,Sand and gravel plants,Tailing lines,Abrasive slurry materials
FREE-VALVE pneumatic rotating disc valves are designed for pressurized and vacuum systems including dense and dilute phase pneumatic conveying systems, discharge and vent applications in steel plant and coal power. The double ceramic sealing faces of the valves are well ground and polished, which is ensure a reliable sealing performance of the valve,the valve is used to replace the dome valve in the pipe line of the ash system.
Features
1. The cylinder piston rod does not contact with the medium directly, which greatly prolongs the service life of the cylinder and has a higher service temperature without damaging the cylinder.
2. The sealing faces of the valve are made toughened engineering ceramics with good abrasion resistance and prolonged service life.
3. Product with customized structural length and connection size is available.
4. The valve disc rotational motion can avoid the ash deposition on the sealing surface� during opening and closing, so the valves have much longer service.
5. The spring between the disc and disc seat is loaded with a floating connection. The spring force of the disc always matches the valve seat, ensures the sealing of the valve, and also helps to compensate for expanding� when� heated� and contracting when cooled ,and sealing surface wear.
6. The blow sweep port or automatic blow sweep device can be set on the valve body according to different operating conditions.

9)Operating Mode: Pneumatic
Application:
FREE-VALVEâ??s Rotating Disc Valves are suitable for coal fired power plant, steel plant, cereals transport system, cement transport systems. In these applications, pneumatic conveying method is used to reduce manpower demand, and improve system efficiency and reliability, and is easy to realize automation.
FREE-VALVEâ??s Pneumatic Ceramic Double Disc Gate Valve is mainly used in feeding and dumping the dry powder and the transport pipeline, which not only adopt toughening ceramic as shut off and wear out resistance material, but also design construction of pressure self-sealing and valve disc auto-rotate, so as to the sealing surface within the dry powder get more wear resistance in process of opening and closing frequently, thereby, which guarantee the high requirements of sealing performance of this valve and long working time.
Features:
1. Sealing pair is made of structural ceramicsï¼?which have perfect performance to resist wear and flushing.
2. Two-side sealing can realized due to double disc structure of the pneumatic ceramic double disc gate valve.
3.� It inserts spring between double valve discs to ensure self- sealing through bi-directional flexible preload pressure� of spring, having characteristics of� low pressure bi-directional sealing and without dust clogging phenomenon in the process of the opening and closing of valve.
4. The valve disc rotational motion can avoid the ash deposition on the sealing surface during opening and closing, so the valves have much longer service.
5. The blow sweep port or automatic blow sweep device can be set on the valve body according to different operating conditions.
