The Scope of Custom Dimensions They Can Accommodate
When it comes to custom ball valve dimensions, Carilovalves approaches each project with engineering precision. The company manufactures ball valves across an extensive size range, typically from NPS 1/4 (DN8) up to NPS 48 (DN1200), though they have demonstrated capability to produce custom sizes outside this standard range when project specifications demand it. This flexibility means whether you need miniature instrumentation valves for laboratory applications or large-scale pipeline valves for municipal water systems, the manufacturing team can develop appropriate solutions.
Their custom dimension capabilities extend beyond simple size scaling. They can modify valve body lengths to fit non-standard installation spaces, adjust port diameters for flow optimization, customize stem heights for actuator mounting requirements, and engineer special flanged or threaded connections that deviate from standard dimensions. This level of customization proves particularly valuable when retrofitting existing systems where new valves must match pre-existing infrastructure rather than conforming to industry-standard measurements.
Material Selection for Custom Specifications
Custom ball valve projects often require specific material choices that align with operational conditions. Carilovalves offers an impressive array of body and trim materials, allowing customers to specify exactly what their application demands. The primary material options include:
- Carbon steel (WCB, WCC, LCC)
- Stainless steel (304, 304L, 316, 316L, 321)
- Alloy steels (F11, F22, F91, F92)
- Duplex and super duplex stainless steel (2205, 2507)
- Chrome-molybdenum alloys for high-temperature service
- Special alloys including Inconel, Monel, and Hastelloy for corrosive environments
For ball and stem components, the selection expands further to include hard-faced coatings like Stellite, tungsten carbide, and chromium carbide. These specialized coatings dramatically extend service life in applications involving abrasive media, high cycle counts, or erosive flow conditions. The ability to specify these advanced materials through the custom order process means customers receive valves engineered specifically for their medium, temperature range, and pressure conditions rather than accepting compromises inherent in catalog products.
Pressure and Temperature Ratings
Understanding that different applications operate under vastly different conditions, Carilovalves engineers custom ball valves to meet precise pressure-temperature requirements. Their manufacturing capabilities cover the full spectrum of industry pressure classes:

Beyond standard connection types, the engineering team can develop hybrid configurations combining different connection styles on a single valve, or create custom flange drilling patterns to match legacy equipment specifications.
Special Feature Customization
Beyond dimensions and materials, Carilovalves excels at incorporating specialized features that address unique operational requirements. Their custom engineering capabilities extend to functional modifications that transform standard ball valves into application-specific solutions.
Bore configurations include standard port (reduced bore), full port (full bore), and V-port designs for throttling applications. The V-port option proves particularly valuable for flow control situations where precise modulation improves process efficiency.
Actuator mounting customization prepares valves for automated operation with pre-drilled and tapped mounting pads compliant with ISO 5211 standards. This eliminates field modification work and ensures proper alignment when pneumatic, electric, or hydraulic actuators are installed.
Blow-out proof stems with anti-static devices provide safety features essential for hazardous location service, meeting API 608 requirements for flammable fluid handling.
Fire-safe designs certified to API 607 or ISO 10497 standards protect against stem and body fires, critical for petrochemical and offshore applications where fire contingencies must be anticipated.
Cryogenic extensions with extended bonnets redirect stem seal adjustment to an accessible location above insulation, simplifying maintenance in LNG terminals and other cryogenic service.
Sealing Material Options
The critical interface between ball and seat determines a valve’s leakage performance and longevity. Carilovalves offers extensive seat and seal material options, allowing specification of compounds precisely matched to service conditions:
