POSI FLATE

Posi-flate Series 585/586 butterfly valves feature seats and discs for application pressures up to 9.3 bar. The Posi-flate Series 585/586 butterfly valves are designed for the most severe of applications. They are ideally suited for very abrasive materials which can reduce valve life. The inflatable seat design provides a better seal by utilizing air pressure to expand the seat against the disc, providing more sealing area and an even pressure distribution against the disc every time. The seat automatically compensates for wear when it inflates against the disc, extending valve life considerably.

Because the Posi-flate disc only makes casual contact with the seat during opening and closing, torque requirements are substantially lower. This ease of movement also allows the disc to come to a perfect 90-degree position every time. Additionally, the smooth profile of the disc helps material flow easier and reduces build-up. For unique fail-safe monitoring, a pressure switch can be utilized to verify a perfect seal.

The Posi-flate 585/586 butterfly valves are available in a wide variety of construction materials including stainless steel and lightweight aluminum. The 585/586 valves are designed to fit PN 10 flanges, and come in sizes 80mm to 600 mm.

Posi-flate has introduced an inflatable seated butterfly valve with a highly polished 316 stainless steel housing and disc. The Series 486 inflatable seated butterfly valve from Posi-flate features a fully machined 316L stainless steel housing. The single piece disc and shaft is available in a number of materials including 316L stainless steel and hastelloy. The disc may be polished to a mirror finish or coated with PTFE, nylon or other high performance coating. The stainless steel valve is ideal for powders, granules, slurries and liquids and is available in sizes 2" (50mm) to 20" (500mm). Typical applications include loading and unloading of process material, sterile air control, and outlet valves for storage containers or hoppers. It is suitable for many applications, such as food, chemical and pharmaceutical.

The Gate Lock Valve Assembly by Posi-flate is a low cost and low maintenance alternative to the traditional rotary airlock feeder and provides a positive seal that can accommodate either full vacuum or pressure up to 6.9 bar. The air-operated seat inflates to provide a long-lasting high integrity seal and easily handles high cycling of dry granular or fine powdered materials. The seat automatically compensates for wear when it inflates against the disc, extending valve life considerably. The Posi-flate Gate Lock Assembly is available in carbon steel and stainless steel in sizes from 2 inch (50mm) to 30 inch (750mm) diameter and in any length desired. Other materials of construction are available upon request.

The Tork-Mate 890 Series actuators from Posi-flate achieve up to 15 million cycles maintenance-free, at low cost. They are ideal for 90° and 180° turn devices such as butterfly valves, ball valves, plug valves and damper valves. They meet the latest NAMUR standards, allowing direct or close coupling of NAMUR designed accessories.  Custom options include Viton seals, high temperature trim, special finishes, stainless steel pinions, special mounting configurations and special coupling configurations.

The Magna Flow Control Valve with an easy to read micrometer dial offers an amazing 1100 precise setpoints to accurately control flow ofgases or liquids. The extremely high CV of the Magna Flow Control Valve enables very high flows with the Series 608 and lower flows with the Series 700 for whatever media is being controlled, up to 13.8 bar pressure or full vacuum. Linear flow characteristics provide easy to set and precise metering of gases and liquids for almost any application where accurate results are required.

Available in light-weight impact resistant nylon, the Magna Flow Control Valve offers superior strength and corrosion resistance, making it ideal for use in hundreds of different applications. Simplicity of construction, with removable top and bottom caps, provides easy disassembly for cleaning or maintenance without removing the valve from service. Proven O-ring seals provide a positive zero leak shut-off. Replacement of seals, if required, is quick and easy because disassembly is simple and fast.
