  2. 2. 2 www.ptpa.ruGate ValvesQuality control has always been an essential element at every stage of manufacturing.Reliability and safe operation of the valves is achieved by: extensive use of professional software for structural design tasks; exhaustive samples test programs for various conditions found in actual industrial applications; regular quality management system (QMS) audits ensuring strict observation of all the applied standards andregulations; acceptance test of every manufactured valve.QMS and Certificates: ISO 9001;  API Spec. Q1;  API 600;  API 6D;  API 607ProfilePTPA has been on the market of industrial valves since 1951. Today it is a huge holding company with over 2000 employeesand a well-developed infrastructure.The valve manufacturing goes through all the technological stages from design and engineering to assembly and test ofthe final product.Complex integration of valve design software and high precision CNC processing has given way to new incentives fortechnology improvement, creativity and innovation.We strive to ensure customer satisfaction by offering the high level of performance and reliability of our products. PTPAalways keeps up with the new trends in the valve industry employing vast experience gained over time and the latestcutting-edge manufacturing technologies. High quality, engineering flexibility and broad production capabilities havealways been the cornerstones of our business.PTPA is a constantly developing company taking every new project as an opportunity to improve overall performance andfulfill the client’s needs.The production range consists of a great variety of valves used in piping systems transporting liquid and gaseous media,such as oil, gas, steam and vapours, water, etc.PTPA offers a broad range of industry leading products for a vast array of applications : oil and gas trunk pipelines, oiland gas processing enterprises, nuclear power plants, chemical industry facilities, still mills, pulp and paper industry, oredressing combines, water works, etc.

Full bore body construction provides clear pass for maintenance and diagnostic equipment.2. Corrosion-resistant overwelding of the trim ensures increased reliability and service life of the gate valves.3. Rolling bearings in the yoke secure decreased effort of the actuator and easier valve operation.4. Usage of thermo expanded graphite for sealing gland provides less stem friction wear-out and extendedservice life of the element.5. Pressure relief plug in the cover provides pressure relief and additional tightness of the gate (by boostingpressure inside).Yoke Gland Camera312 54

Seats with double sealing (primary-«metal to metal», secondary-«metal to elastoplastic») provideextended service life.3. Corrosion-resistant gate protects the trim from abrasive wear-out and line medium deposits.4. Drain pipe inside gate valve is designed to remove sediments containing hard admix. Drain pipe isprotected from damage and freezing at low temperatures. Threaded port on the drain pipe for dewaxingdevices and air bleed hoses connection. The port as well as the inlet in the bonnet for pressure relief plugcan be used for leak test of the gate valve.5. The gate valve can be repaired without removal from pipeline. Removable polyurethane ring gasketsand clamp connection «body-to-cover» ensure high level of maintainability, quick assembly-disassembly ofgate valve and serviceability.6. Usage of thermo expanded graphite for sealing gland provides less stem friction wear-out andextended service life of the element.Gland Camera652134
