Machining & Grinding Services
JS Machine & Valve provides valve machining and grinding services to restore sealing surfaces, critical tolerances, and component integrity. These services are performed both on-site and in-shop, depending on access, scope, and project requirements.
Restoring Fit, Function & Sealing Performance
Machining and grinding are essential to restoring valve performance. Over time, sealing surfaces, bores, and critical interfaces can wear, deform, or degrade due to service conditions.
JS applies precision machining and grinding to return these surfaces to proper tolerances and finish.
Common Applications Include:
- Restoration of sealing surfaces and seats
- Bore repair and dimensional correction
- Surface finishing and tolerance recovery
- Preparation for weld repair or component replacement
- Final finishing prior to assembly and testing
Machining & Grinding Services
Flange & Surface Restoration
Reconditioning flange surfaces to restore proper sealing and alignment.
Bore Repair & Line Boring
Machining bores and internal diameters to correct wear or distortion.
Seat & Sealing Surface Grinding
Grinding and finishing seats to restore sealing performance.
Taper & Precision Grinding
Restoration of critical geometries and surface finishes.
Component Machining
Machining of valve components to meet required tolerances and specifications.
Field & Shop Services
Performed Where the Work Makes Sense
Machining and grinding services are performed in both field and shop environments depending on project scope.
- Field machining is used for in-place repair, outage work, and situations where removal is not practical
- Shop machining and grinding is used when tighter control, larger equipment, or full rebuild scope is required
This flexibility allows each project to be completed using the most efficient and appropriate approach.
Capabilities & Applications
JS Machine & Valve performs machining and grinding across a wide range of valve types and service conditions.
Capabilities Include:
- Precision machining of valve components
- Grinding and finishing of sealing surfaces
- Bore restoration and dimensional correction
- Surface preparation for repair or assembly
