In plant operations across the US, non-lockable valves are a leading cause of safety incidents, costly shutdowns, and compliance fines. According to OSHA, over 60% of process safety events involve accidental valve actuation during maintenance.
Real scenario: A Texas petrochemical plant replaced 47 standard ball valves in one year due to lock‑related failures. After switching to Thriveon’s lockable flanged valves, they reported zero safety violations and 58% fewer valve replacements over 18 months.
Handle with 3‑position padlock hasp (compatible with ¼″ to ⅜″ shackles). Valve can be locked fully open, fully closed, or partially open – meets OSHA LOTO and ANSI Z535 standards.
Investment cast body with PTFE/RPTFE seats for corrosive media (acids, chlorides, seawater). Anti‑blowout stem design and ISO 5211 mounting pad.
Full bore design minimizes pressure drop. Passes API 598 fire‑safe test and ISO 5208 rate A (zero bubbles). Suitable for 1,000+ psi working pressure.
Inventory ready in 10–15 days for standard sizes (½″ – 12″). Express shipping via FedEx, DHL, or air freight. Free technical drawings within 24 hours.
