Kele has been watching from the sidelines of the ball valve marketing game long enough. Within the huddle we've been unimpressed with the penalty prone manual ball valves used today in the automatic HVAC game. Fumbles such as leaky valve stems and inferior packing may be OK for the semi-pro game, but is unacceptable to the professional. Our scouts have discovered a 1st round draft pick that you can rely on in tough, long yardage situations. Our requirements include eliminating the leaky stems, intestinal fortitude in construction, stamina, and most of all the performance stats to justify being called a professional HVAC control valve on the KELE team.
The first requirement was to solve leaking stem problems. The stem and packing of the existing ball valves in the game today are designed specifically for manual on/off control. HVAC control by definition demands frequent re-positioning and endurance. The Kele valve has packing designed specifically for frequent re-positions and no maintenance. The O-ring design is typically used in industrial ball valve designs and is so leak resistant that the packing nut is permanently positioned. The linkage, which couples the valve to the actuator, is also critical to success. Side loading of the stem causes added wear to one side of the packing and shortens the leak free performance of any valve. This valve comes to you pre-assembled, with the linkage and actuator, to eliminate the possibility of side loading and to ensure long, leak free performance.
Intestinal fortitude is another contributing factor to this valve's superior performance. Stainless steel is used for the ball and stem of our draft pick as opposed to the chrome plated competition. As the water is fouled with debris the chrome is more easily scarred and ruined while the stainless steel remains on the job. Break-away torque is also reduced because the seat material microscopically adheres to the pores of the ball valve. This happens to all ball valves but is worse in the chrome-plated ball thus increasing the size of the most costly part of a valve, the actuator.
High maintenance is the aftermath of many ball valve installations. Due to the O-ring and superior manufacturing technique, the valve-packing nut is sealed, which eliminates the need for valve maintenance. All other HVAC ball valves require periodic maintenance to tighten the packing nut, which at some point will bottom out and require replacement. This type of hidden cost may be good for service contracts but is not desirable when the outcome results in callbacks, damaged ceiling tiles and customer dissatisfaction.
With all of the promised quality discussed above, Kele needed some assurances that this ball valve would live up to expectations. We visited the manufacturer's testing facility and verified that the testing program was rigorous and fair to all the competitors. The statistics conclude that the Kele assembled valve was 10 times better than the competition and was the only one up to the hazards of the professional HVAC control game.
Although free agent top quality players are expensive, we have negotiated an excellent deal for your division of the "HVAC". We have assembled a complete team from backfield 1/2'' sizes, to linemen 2'' sizes, in three-way and two-way configurations. Any play can be called with a complete selection of actuators for 2 position, tri-state, and proportional control. Special team applications are also possible with spring return and non-spring return option plays. The Kele team is suited up and ready to play on your turf. Just call your Kele coaching staff because Kele not only takes the ball, we run with it.
24 valves tested (6 of each type)
