Valves & Actuation
Engineered and Flow Tested for Superior Performance
Designed for quick, positive seal-off with minimum turbulence, low restriction and maximum fluid transfer, this industrial-grade ball check valve is used in a wide variety of industrial and chemical processing applications.
Heavy-Bodied PVC or CPVC Construction
Spears True Union Ball Check Valves never rust, scale or pit, providing exceptional chemical and corrosion resistance. Strong buttress-type threads on the union nuts allow higher pressure-handling capability and quick in-line installation and servicing.
- Spears computer-engineered design provides superior fluid flow with minimum turbulence. Eliminates “chatter” often encountered in ball check valves.
- Maximum Internal Pressure of 235 psi at 73°F for the most demanding applications of 1/2" - 4" valves.
- All Spears True Union Ball Check Valves are NSF Certified for potable water use.
Spears® True Union 2000 Ball Valves provide maximum versatility with fully interchangeable (with Series 2000 Ball Check Valves and 3-Way Ball Valves) valve cartridges. Provides for easier system design modifications and upgrades in multi-phase projects, or anywhere changes in valve type are desired. All True Union Industrial series ball valves feature a unique lockout handle incorporated as a standard feature, eliminating the need for bulky and expensive lockout covers. Choice of high grade EPDM or FKM o-rings allows application-specific selection for optimum chemical resistance.

Spear’s innovative design departs from traditional liner-seat type valves to eliminate seat creep, reduce operating torque and provide positive seal off. Ideally suited for flow control or throttling, this high performance valve is offered with a full variety of options for greater application versatility. Pressure rated to a maximum internal pressure of 150 psi at 73°F - including dead end service. Heavy blow-out proof 316 stainless steel stem is standard on all valves. PTFE-coated Stainless steel or titanium stems are available on request.
