One-piece forged body
Two-piece stem design: Upperstem threads cold rolledand lower stem hardened for high strength and smooth operation
Accidental valve disassembly disabled by union bonnet construction
Upper stem thread lubricant isolated from system media
Linear instead of rotary movement of the rising, non-rotating stem minimizes packing abrasionand reduces the friction between the seat and the tip
Safety back seating seal in fully open position
Panel mounting available
Steady and durable fastening of the handle by double lock-pins
Handles of different colors available
