Threaded Connections
These valves feature threaded connections for installation in compatible threaded piping systems. Confirm thread dimensions, thread standard, and mating connection compatibility before installation.
Safety Block Valve Design
These threaded valves belong to the manufacturer's Safety Block series. The Safety Block designation identifies this valve family and should be considered when selecting a replacement or matching an existing installation.
Single Union Construction
The single union configuration provides a union connection on one side of the valve. This differs from true union configurations, which have union connections on both sides. Confirm that the single union arrangement matches the installation requirements.
White PVC Body
White PVC construction provides a nonmetallic valve body for compatible piping systems. Verify chemical compatibility and operating temperature limitations before installation.
EPDM Seals
All three threaded configurations use EPDM sealing material. EPDM compatibility varies depending on the fluid, chemical concentration, temperature, and service conditions. Confirm suitability for the intended application.
Manual Flow Control
The ball valve mechanism provides manual quarter-turn opening and closing. The valve is intended for use in threaded piping systems that meet its material, pressure, and installation requirements.
150 PSI Pressure Rating
Each available size has a listed pressure rating of 150 PSI. Review the manufacturer's specification sheet for applicable temperature-related pressure limitations and service restrictions.
Size Selection
Choose the 1/2", 3/4", or 1-1/4" threaded configuration based on the required nominal pipe size. Verify the thread standard and compatibility with the piping system before ordering.
Threaded vs. Socket Connections
These are threaded ball valves, not socket-style valves intended for solvent-cement connections. Select the correct connection type for the installation.
