Metal Seated Ball Valves
Precision metal-to-metal sealing engineered for severe abrasive slurries, high temperatures up to 550°C, and critical bidirectional bubble-tight shutoff in chemical, petrochemical, oil & gas, and power generation infrastructure.
Engineered for Severe Service, Extreme Temperature & Abrasive Fluid Isolation
ENGIPRO SOLUTIONS LLP metal-seated ball valves are engineered to deliver long-lasting durability and premium performance in the most demanding operating environments. Designed with precision metal-to-metal sealing, these valves provide reliable, leak-proof shut-off under high-pressure and high-temperature conditions, ensuring consistent performance even in severe industrial applications.
Ideal for industries such as oil and gas, petrochemical, power generation, and other heavy-duty process applications, our metal-seated ball valves are built to withstand extreme operating conditions while maintaining excellent sealing efficiency. Their robust construction offers outstanding resistance to wear, corrosion, and abrasion, making them suitable for handling aggressive media and challenging service environments.
With smooth operation, low maintenance requirements, and dependable long-term performance, ENGIPRO metal-seated ball valves provide the accuracy, strength, and reliability required for critical industrial processes. Designed to maximise operational efficiency and service life, they are the ideal choice for applications where durability, precision, and consistent performance are essential.
Special Features & Engineering Construction
Engineered to satisfy ASME B16.34, API 6D, and ISO 17292 requirements for severe industrial isolation.
Modular Body Construction
Available in One-Piece (unibody), Two-Piece (split body), and Three-Piece bolted designs for effortless maintenance and in-line valve servicing.
Fire-Safe Certified Design
Tested and certified per API 607, API 6FA, and ISO 10497. Secondary metal seating provides reliable shutoff even after soft seal destruction in fire exposure.
Anti-Blowout Stem & DBB
Internally assembled bottom-entry stem collar prevents stem ejection under extreme system pressure. Integral Double Block & Bleed (DBB) capabilities.
Low Operating Torque
Belleville spring live-loaded seat design maintains constant sealing force while minimizing friction, enabling smaller and more cost-effective actuator sizing.
Low-Temp Lip Seals
Spring-energized polymer lip seals engineered specifically for cryogenic and low-temperature duties, ensuring resilient sealing at sub-zero service.
Custom Stem Extensions
Extended bonnets and stems available for thermal insulation, cryogenic cold-box applications, buried service, and high-temperature radiation barrier zones.
ISO 5211 Actuator Pad
Standardized ISO 5211 top mounting flange for direct connection to pneumatic double-acting/spring-return actuators, quarter-turn electric motors, or hydraulic packages.
Zero Leakage Shutoff
Precision ground and matched ball-to-seat contact delivers bubble-tight bi-directional isolation conforming to API 6D and API 598 zero-leakage standards.
