This tank is made of carbon steel with epoxy finish, mounts to supply piping, 1/2 inch MNPT system connection and a 0.302-32 inch charging valve connection (standard tire valve) to facilitate on-site charging of the tank to meet system requirements. The maximum working pressure is 75 PSI (5.3 BAR).
- Precharged to 12 psi
- Rugged flexible butyl diaphragm
- Inline and free standing models
- Steel construction
The Pro-Pal Ball Drain is a full port forged brass ball valve. It features a hi-flow hose drain, adjustable packing glands, and reversible handle. The exclusive adjustable flow path allows for draining from either side of the ball.
- Replaces 4 components; eliminates 3 leak paths; saves nearly 30 minutes in labor
- Eliminates assemblies needed to isolate and drain any portion of a piped system
- Avoids reduced port alternatives
- Certified to NSF/ANSI 61 & 372
- Reversible handle for added versatility
- Exclusive adjustable flow path allows for draining from either side of the ball
The Taco LWCO provides reliable protection for all types of boilers, from small residential hot water boilers to large industrial steam boilers. The boiler's minimum safe operating water level is specified by each manufacturer. Should the water level dip below that specified level, heat will accumulate quickly causing significant damage to the boiler and a potential external safety hazard. The Taco LWCO prevents this hazard from occurring. The LWCO can be used as a primary or secondary low water cutoff on steam boilers up to 250 psi, a primary limit control on hot water boilers or to protect pumps from running dry in condensate receiver tank applications. The LWCO can also activate alarm systems or automatic water feeders.
- Patented adjustable probe sensitivity
- External LEDs and simplified wiring for easy installation and testing
- Automatic or manual reset mode
- Standard on-board (NEMA 1) or remote (NEMA 4) probe
- LT models include external test button, adjustable Delay on Break (DOB) and Delay or Make (DOM) features
2-way on-off low voltage valves consist of an actuator and valve assembly for controlling the flow of hot water. For use in hydronic controls. Press-connect fittings.
- All models may be installed without disassembling the valve
- Manual opener (on all models, except straight-through, normally open valves) for valve operation on power failure
- Valve returns to automatic position when power is restored
- Compact construction for easy installation
The Isolator is a uni-flange ball valve that isolates a circulator pump, allowing virtually no air into the system during pump replacement or service. Its innovative design combines multiple components into a single forged brass body that saves time, labor and space. The Isolator has revolutionized the installation of circulator pumps and has evolved into the largest flanged ball valve program in the industry today, featuring patented technology with further patents pending. Designed for use with water, oil, glycol mix in residential or commercial residential plumbing, commercial plumbing, heating systems. Refer to specification sheets for additional technical information. All Webstone products are backed by a limited lifetime warranty.
- Easily Isolates the Pump for Replacement
- Replaces 8 components, eliminates 7 leak paths, saves approximately one hour in labor
- Fits virtually any standard circulator pump
- Available with slotted holes for high velocity pumps
- Prevents Electrolysis and Eliminates Galvanic Corrosion
- Rotating Flange is Secured by a Snug-Fit Snap-Ring that Provides Greater Control Over Positioning During Installation
