Float Valve Revolutionizes Car Wash Maintenance Programs
|
||||
| One of the biggest headaches in the car wash maintenance industry is the float valve. In the past, float valves were cumbersome, inefficient and used oversized floats and long stems to create mechanical leverage. This leverage was then used to shut off the valves which caused wear and tear on the valve parts. Expensive cast brass bodies were needed to support the water | pressure and flow required to operate water systems for car washes. All of these factors led to continual repair and or replacement of float valves at a high cost to all people involved. The CLEVELAND VALVE COMPANY has been in the business of solving float valve problems for a number of applications throughout the industry. Some of their revolutionary designs have been | incorporated for use in applications ranging from evaporative cooling towers to livestock watering tanks. Now they have a new valve designed for car washes. This valve eliminates all of the problems caused by mechanical float valves as well as outperforms any other valve on the market with respect to valve life, inlet pressure and water flow. | ||
| Compact Size And
Design Make Cleveland's Stage 2®
Valve Unique.
|
||
| The CLEVELAND VALVE COMPANY used existing technology to design a valve that is compact, yet provides unprecedented flow rates for a valve of its overall size. The Stage 2 Valve works with water pressure and has operating range of 5-110 PSI. with flow rates up to 250 GPM (88 GPM at 60 PSI). The valve design provides | for POSITIVE SHUTOFF eliminating chatter, water hammer and blow by. With only a 2 ½" float needed to shut the 1 ½" NPT valve off, bulky 8", 10" or 12" floats are eliminated. This fact along with a short lever arm allow the valve to operate in a fraction of the space needed for a standard mechanical valve. | |

|
||
| How Does The Competition Measure Up? | ||
| Stage 2® valve measures 14" from valve to float. The float measures only 3.5" sq x 2" thick. |  |
|
| Cleveland Valve's Stage 2, 1.5" NPT | ||
| Conventional valves measure 20" to 36" from valve to float. The floats can measure from 6" dia. to 10" dia. |  |

Stage 2® Valve Works With Water Pressure |
|
|
While other valves use leverage created by water levels to force valves closed, the Stage 2 valve opens and closes using differential water pressures to activate a diaphragm, eliminating most wearable parts. |
|
|
|
 |
| Open Position | Closed Position | |
| Open - When the pilot valve is in the open position, water enters the inlet under pressure. The diaphragm is forced into a nesting position in the body cavity. Water flows through the small hole in the diaphragm and thru the outlet at the pilot valve to the reservoir. The valve is now open. | Closed - When the pilot valve is in the closed position, water passing through the small hole in the diaphragm is trapped in the body cavity. The diaphragm is slowly forced into the inlet opening stopping the flow of water through the valve. | |
|
|
|
Conventional Valves are made from precision machined brass parts and use water levels to create leverage on the stem which forces the Plunger inward to close the valve. As the valve begins to close, chattering, blow by and undue stress occur causing the valve to war out at the plunger, seat , and cup. |
|
| Stage 2® Valve Can Take The Heat | |
| People
who own, operate and maintain car wash systems already know how
hot water, microbus and ozone molecules can reek havoc on a water
system and its moving parts. To help combat these problems
the Cleveland Valve Company makes all of its housing s from glass
filled nylon and can operate at temperatures up to 140°F.
The diaphragms are made from BASF Elastollan #1185A.
Hydrolytic degradation occurs in other polyester-based polyurethanes
after short periods of exposure to hot water, moisture vapor or
tropical changes.
Elastollan 1185A ether type Thermal Polyurethanes exhibit better hydrolytic stability when compared to other commercially available ester type TPUs. (See figure 1) It is also resistant to all microbiological and Ozone exposure. Even if your system is running too hot or is contaminated by stagnant water conditions, where other valves would stop working, the Stage 2 Valve will continue to operate as normal. |

| Compact Size Results in Less Shelf Space For Distributors/O.E.M.'s | |
| Conventional
valves have long stems and large floats. This creates a
problem when trying to keep them in stock. With just a few
valves and floats to be stocked, an entire shelf can be
filled. The Stage 2 Valve comes prepackaged in a single
cardboard box. The box for the 1" NPT valve houses the
body, stem and float in a 6" x 6" x 6" box with a
shipping weight of just .77 lbs.
(See Picture >) Six of these boxes come in a case that is 7" x 14" x 19". Saving shelf space is a major concern for stocking distributors and O.E.M.'s The Stage 2 valve directly addresses this |
|
| problem as well as eliminates the need to constantly search for the proper stems and floats for each valve sold. | The Stage 2, 1" NPT valve's Body, Stem, and Float are all packaged together in a convenient 6" x 6" x 6" box and all boxes are clearly labeled. |
