Industrial Ball Valves
High-integrity quarter-turn ball valves engineered for critical isolation in high-pressure, severe-temperature, and abrasive flow environments. Designed with precision spherical closures, low operating torque, and certified bubble-tight bidirectional shut-off across global energy and process pipelines.
Precision Flow Isolation, Low Operating Torque & Severe-Service Reliability
ENGIPRO SOLUTIONS LLP manufactures high-performance industrial ball valves engineered to provide positive bidirectional shut-off, low operating torque, and high flow capacity with minimal pressure drop. Built for high-reliability process isolation across chemical plants, oil refineries, gas pipelines, and power utilities, our ball valves are compliant with API 6D, ASME B16.34, API 608, and BS EN ISO 17292 standards.
Our product range encompasses both Floating Ball Valves (DN 15 to DN 250 / 1/2" to 10") where upstream pressure pushes the ball securely into the downstream seat ring, and heavy-duty Trunnion Mounted Ball Valves (DN 25 to DN 600 / 1" to 24") where the ball is anchored between rigid mechanical trunnions with spring-energized floating seats.
Depending on process media, operating temperatures, and slurry content, ENGIPRO ball valves are available in resilient soft-seated configurations (PTFE, RPTFE, PEEK) for bubble-tight isolation, and supersonic HVOF-coated metal-seated configurations (Tungsten Carbide, Chromium Carbide, Stellite 6) capable of handling abrasive particulates and severe heat up to 600°C.

API 6D • BUBBLE TIGHT
Soft Seated Ball Valves
Precision thermoplastic seats (Virgin PTFE, RPTFE, PEEK) delivering zero-leakage bubble-tight shut-off for process fluids, gas lines, and utilities.
SEVERE SERVICE • 600°C
Metal Seated Ball Valves
Hard-faced with supersonic HVOF tungsten carbide or Stellite for abrasive slurries, high temperatures up to 600°C, and erosive catalyst fines.
API 6D • DBB STANDARD
Trunnion Mounted Ball Valves
Mechanical trunnion-anchored ball absorbing pipeline loads, spring-loaded floating seats, and certified Double Block & Bleed (DBB) isolation.
Special Features & Engineering Construction
Engineered to satisfy API 6D, ASME B16.34, and ISO 14313 benchmarks for critical hydrocarbon transmission and process containment.
Double Block & Bleed
Simultaneous upstream and downstream sealing allows the central body cavity to be bled safely through a dedicated port to confirm seat isolation integrity.
Fire-Safe Certified
Designed and certified in accordance with API 607 and API 6FA. Features secondary metal-to-metal seating upon soft seal burnout during an emergency fire.
Blowout-Proof Stem
Internally assembled stem with integral retention collar prevents stem blowout under full system pressure, ensuring operator and plant safety.
Low Operating Torque
Self-lubricating PTFE/metal composite trunnion bearings absorb line pressure loads, enabling effortless actuation with smaller actuators and gear units.
Self-Relieving Cavity
Spring-loaded floating seats automatically relieve trapped liquid overpressure back into the pipeline when thermal expansion occurs in the closed cavity.
Emergency Sealant Ports
Fitted with standard stem and seat emergency sealant injection fittings with internal check valves to restore seal integrity during field upsets.
ISO 5211 Direct Mounting
Standard ISO 5211 mounting flange accommodates direct coupling to pneumatic scotch yoke, electric rotary, or hydraulic emergency actuators without brackets.
Anti-Static Grounding
Integral conductive spring-loaded plungers ensure electrical continuity between stem, ball, and valve body, eliminating static electrical discharge hazards.
