Valves "D" - DN150-DN300; PN6.3-PN16 MPa
PURPOSE AND SCOPE
They are used as locking arms for installation on processing lines carrying version operating mediums:
- Material version С — non-aggressive natural gas, oil, oil products and other non-aggressive mediums with the temperature from -60°С to +100°С (a possible version is to +250°С);
- Material version Н and М — gases containing aggressive agents (hydrogen, oxygen, sulfur, hydrogen sulfide, etc.) and flow aggressive mediums – solutions of acids and alkalis, etc. at the temperature from -60°C to +250°C.
ADVANTAGES AND DETAILS OF CONSTRUCTION:
- valve construction is modular, it consists of one-piece body and two joints connected with body by stud bolts that provides its maintainability;
- using of spring-load portable polyurethane seats in conjunction with a double-beat plug provides valves hermiticity of class “A” during the whole period of their operation;
- support bearings are made of metal-fluoroplastic belt and provide reliable operation during the whole period of operation, do not need lubrication and maintenance;
- valves are equipped with a system of constrained sealing grease supply to the zones of spindle and seats seal providing recovery (if necessary) of hermiticity in the process of operating. Unified fittings for sealing grease supply allows quickly join adapter of the packing device;
- dismountable spindle ball valve allows safe interchanging of spindle soft seal on the acting pipeline (plug position — «closed»);
- globe valves are made with pneumatic and electric drive of both above ground and under ground version;
- globe valves with pneumatic drive are completed with VCM ( valve control module) with integral limit switches on 24 V and 110 V.
