Portable machine for in situ repair of stop (gate) valves

Portable machine for repair of gate valve

PORTABLE MACHINE FOR IN SITU REPAIR OF STOP (GATE) VALVES

PURPOSE:

Portable unit is designed for grinding and lapping of the sealing surfaces of the housings and spools of the stop valves without their dismantling from the pipeline.

MACHINED-SURFACE TYPES:

• sealing surfaces of the stop valve housings and spools.

DN OF VALVE:

• 32...200 mm (1...8'')

 

COMPLETE SET:

• portable unit (А);
• professional pneumatic drive (Atlas Copco) (В1) and electric drive Bosch (В);
• stand for spool machining (С);
• multi-function installation device (D);
• replaceable grinding and lapping disks;
• a set of self-adhesive grinding rings;
• air-preparation unit with a sleeve for compressed air supply;
• plastic case;
• set of spare parts and accessories.

EQUIPMENT ADVANTAGES:

• It is unique for work with nonflanged valves (grinding and lapping of the sealing surfaces of the housings directly in the pipeline without cutting out the valves with further welded connection).
• The high quality of machined surface is achieved due to the design of the working head and the mandrel, which generates complex plane parallel motion and the required clamping force of the tool.
• Small weight of the unit makes it convenient for use at hard-to-reach locations.
• The set includes the stand for spool machining as well as numerous machining disks, pneumatic and electric drive, and the air preparation unit.
