Since 1986 JSC Sumy NPO has occupied firm position in CIS countries market as the main manufacturer of pipeline valves for gas industry.
The valves manufactured by the company are based on high technology stamped and welded design with wear-resistant elastomer seals which provide the reliable valve tightness.
The product is distinguished by high quality, ease and convenience for service.
Designed for operation as shut-off devices on process lines transporting non-aggressive natural gas and other non-aggressive media with temperature from -60°C to +80°C.
Design feature:
- ball valve body consists of two welded stamped semi-bodies, that excludes the possibility of valve unit depressurization concerning the external environment;
- sealing of gate valve is made of elastomeric material with high wear-and erosion-resistant;
- high tightness is achieved by compression of both seats to the end plug;
- valve is designed as «end plug in the supports» with self-oiling bearings made of metalfluoraplastic that makes easy valves control ball valves with Direct Gas Actuator with Liquid Damper and Hand Pump;
- cylinderless actuator construction distinctly reduces the volume of pressure liquid of actuator hydraulic system;
- direct Gas Actuator with Liquid Damper and Hand Pump are filled in the pressure liquid;
- ball valves control units have integral terminal plates, end switches.
And they don’t require additional piping; - control Voltage – 24, 110 and 220;
- it is possible to complete ball valves with electric actuators;
- it is possible to manufacture ball valves of underground installation type with application of corrosion-resistant polymer coating.
Installation type – over-ground and underground. The average service life before overhaul is no more 40 years.
Technical data is specified in the Catalog.
Designed to automatically prevent back flow of working medium when transporting non-
aggressive natural gas and other non-aggressive media with temperature
aggressive natural gas and other non-aggressive media with temperature from -60°C to +80°C.
Design Features:
– check valves of rotating type;
– the availability of liquid dampers DN 300…500 and pneumatic dampers DN 700 and over makes possible to reduce impact loads;
– one-piece stamp-welded construction of check valves body;
– high maintainability;
– low pressure loss.
The average service life before overhaul is no more 40 years.
Technical data is specified in the Catalog.
Designed for protection of compressor
flow part when restriction entry.
Design features:
– minimum hydraulic resistance due to the fact that the area of punching is more than flow area of the pipeline;
– one-piece stamp-welded construction of the body;
– detachable screen, mudhole (from DN 700 and over)
– high maintainability.
The average service life before overhaul is no more than 40 years.
