Apollo 75‑105‑41 1″ Bronze Ball Valve is a pad‑lockable, drain‑equipped FNPT valve rated 600 psi/150 psi steam with strengthened PTFE seats and blow‑out‑proof stem.
Apollo 75‑105‑41 1″ Bronze Ball Valve is a robust, two-piece FNPT valve engineered for high-pressure, safety-conscious environments. This professional-grade valve features a pad-lockable steel lever and automatic downstream drain, enabling maintenance isolation without pressure build-up. Rated at 600 psi Cold Working Pressure (CWP) and 150 psi saturated steam, it reliably performs in demanding fluid, air, or steam systems.
Constructed from B584‑grade bronze with a chrome-plated B16 brass ball and RPTFE seats and seals, the Apollo 75‑105‑41 1″ Bronze Ball Valve offers wear-resistant performance and tight shutoff. The blow-out-proof stem and adjustable MPTFE packing ensure durability and leak prevention throughout intensive use.
This valve has a standard-port orifice of 0.87″ and delivers a flow coefficient (Cv) of 43 GPM, balancing strong flow rates with compact, manageable form. The zinc‑plated steel lever includes a vinyl grip and pad-lock feature for safety lockout without modifying hardware.
