Ensure that the valve, stem and float used are rated for your maximum inlet pressure and GPM flow rate. Check minimum stem length and minimum float ball size. This may vary according to your application and maximum inlet pressure.
For non-standard assemblies, if you see that the float is completely submerged without shutting off, or if the float "bounces" all by itself without stopping, it usually means that the float is too small or the stem is too short to work reliably at that pressure. If your particular application requires a shorter stem, bent stem and/or smaller float than recommended, it will reduce the amount of leverage or buoyancy available to close the valve, thus lowering the maximum rated inlet pressure. A pressure regulator can be used to compensate for a reduction in the inlet pressure. Instead of modifying the assembly or installing a regulator, Control Devices, LLC recommends selecting a smaller standard assembly that fits your available space, or a smaller orifice size to gain reliable shut-off at higher pressure. Please note, by reducing the inlet pressure or selecting a smaller orifice size the GPM flow rate will be reduced. To avoid a reduction, consider using two smaller valves instead of one larger valve to meet both your GPM and space requirements.
Increasing or decreasing the inlet pressure at the valve will often cause a slight increase or decrease in the water level setting at shut-off. The water level, at shut-off, reaches maximum height at the maximum possible inlet pressure provided; therefore, when the inlet pressure changes, the amount of change in the water level is related to the volumetric displacement of the float. This is a normal property of float valves. Maximum accuracy and repeatability is obtained when the inlet pressure remains constant. If varying inlet pressures are expected, be sure that your application design allows for slight changes in the water level at shut-off.
Always ensure that the float valve is mounted rigidly with respect to the water surface. If the tank wall, supply pipe, or mounting bracket is able to flex or move, it may cause the valve to vibrate, oscillate or "sing" very loudly. As the valve starts to close, the pressure increases, causing the valve body to flex away from the water surface. When the valve body moves away, the valve opens wider and the pressure decreases, causing the valve body to flex back to its original position. At this point, the valve body starts to close again, creating a cycle of oscillation. A rigid mounting system prevents the potential for this kind of vibration or oscillation to occur.
The tank or reservoir should always include provisions for some kind of overflow drain system capable of handling the maximum GPM flow rate. Dirt, physical damage, excess pressure, loose or improper adjustment, normal wear, or mineral deposit buildup over time may prevent the valve from fully closing. An overflow drain system will prevent the possibility of unexpected flooding, should this occur.
Normal wear over the life of the valve may cause the water level setting at shut off to gradually increase slightly, resulting in occasional readjustment.
Slight leakage or dripping around the valve plunger or cup seal when the valve is in the open position is normal for all float valves of this type. If the cup seal was tight enough to prevent any leakage or dripping at the plunger, the plunger may bind and stick open or closed. The cup seal prevents excessive spray from occurring around the plunger and directs the flow to the valve outlet without causing the plunger to bind. Water cannot drip from around the plunger when the valve is fully closed.
A float valve of this type closes gradually rather than in a "snap action" ON/OFF. Slight leakage or dripping from the outlet as the water level reaches the shut-off point is normal, unless the seat or disc is worn. If the float arm or stem is lifted slightly and the dripping stops, it indicates the seat and disc are functioning normally, and the water level is just not high enough to achieve full shut-off.
Consider carefully where the valve will be mounted. It is best to avoid bending the stem, if possible. Bending the stem too much shortens the effective length of the stem reducing the amount of leverage available to close the valve. Instead, adjust the liquid level with a short arm and a thumb screw or an adjusting screw. This may vary according to your particular application and maximum inlet pressure. Custom bent stems can be purchased if exact requirements are provided.
The primary purpose of a safety valve is to protect life, property and the environment. Safety valves are designed to open and release excess pressure from vessels or equipment and then close again.
The function of safety valves differs depending on the load or main type of the valve. The main types of safety valves are spring-loaded, weight-loaded and controlled safety valves.
Regardless of the type or load, safety valves are set to a specific set pressure at which the medium is discharged in a controlled manner, thus preventing overpressure of the equipment. In dependence of several parameters such as the contained medium, the set pressure is individual for each safety application.
A “safety valve” is an exception to mandatory minimum sentencing laws. A safety valve allows a judge to sentence a person below the mandatory minimum term if certain conditions are met. Safety valves can be broad or narrow, applying to many or few crimes (e.g., drug crimes only) or types of offenders (e.g., nonviolent offenders). They do not repeal or eliminate mandatory minimum sentences. However, safety valves save taxpayers money because they allow courts to give shorter, more appropriate prison sentences to offenders who pose less of a public safety threat. This saves our scarce taxpayer dollars and prison beds for those who are most deserving of the mandatory minimum term and present the biggest danger to society.
The Problem:Under current federal law, there is only one safety valve, and it applies only to first-time, nonviolent drug offenders whose cases did not involve guns. FAMM was instrumental in the passage of this safety valve, in 1994. Since then, more than 95,000 nonviolent drug offenders have received fairer sentences because of it, saving taxpayers billions. But it is a very narrow exception: in FY 2015, only 13 percent of all drug offenders qualified for the exception.
Mere presence of even a lawfully purchased and registered gun in a person’s home or car is enough to disqualify a nonviolent drug offender from the safety valve,
Even very minor prior infractions (e.g., careless driving) that resulted in no prison time can disqualify an otherwise worthy low-level drug offender from the safety valve, and
The Solution:Create a broader safety valve that applies to all mandatory minimum sentences, and expand the existing drug safety valve to cover more low-level offenders.
