Lead-Free Solenoid Valves

Lead is a highly poisonous substance. Manufacturers of drinking water fountains, reverse osmosis systems, coffee makers, and commercial kitchen equipment are affected by strict US safety standards. Soldering flux having a lead content of more than 0.2 percent, or a weighted average of 0.25 percent lead in the wetted surfaces of pipes, pipe fittings, plumbing fittings, and fixtures, cannot be used in a lead-free system. Lead-free is a cumulative term under the law. 

As a result, Ives Equipment and ASCO offer various lead-free valve options that comply with the new rules, are NSF certified, and are available in the industry's most comprehensive range of pipe sizes, pressure or temperature ratings, and flow coefficients. 

Customers can meet the safety regulations for components of purifying water systems by using reliable, readily available NSF-certified fluid control products and solutions.  ASCO offers the broadest selection of pipe size, pressure or temperature ratings, and flow coefficients in the market, all of which meet the new rules. 

LEAD-FREE BRASS SOLENOID VALVES

ASCO offers lead-free brass construction in their general service solenoid valves with the same proven performance, reliability, and quick availability as their brass solenoid valve equivalents. 

PLASTIC AND COMPOSITE SOLENOID VALVES

Solenoid valves made of composites or plastics have the benefit of being lead-free from the outset. They come in a variety of pipe diameters and shapes, including those used in drinking water systems. For residential and commercial drinking water services, these valves are presently possibly the most popular option. ASCO offers a comprehensive selection of NSF-certified composite valves to fulfill the needs of the industry. 

STAINLESS STEEL VALVES

Stainless steel, another lead-free option, provides compliance in a durable metal body. This material's valves have the most extensive range of properties in categories, including pipe size, pressure or temperature ratings, and flow coefficient in the industry (Cv).

Fixed Gas Detection Factory Service from Sensidyne and Ives Equipment

Fixed gas detectors are commonly found in large industrial facilities where explosive or noxious fumes, vapors or liquids exist.  Fixed gas detectors are used to identify significant leaks and provide an early warning of  leaking from a specific system. Relays and adjustable alarm point settings are used to configure fixed gas detection systems. Fixed gas detectors respond swiftly to atmospheric threats thanks to these settings. Opening and closing ventilation and exhaust fans, triggering visual and audio alerts, and closing valves are just a few of the functions they can do. 

Industrial safety professionals understand how critical it is to keep essential safety instruments calibrated and serviced. Infrequent sensor calibration reduces the accuracy of gas detection readings and may result in the failure to detect gas leaks, resulting in an unprotected zone. 

And now might be a good time to perform some preventative maintenance.

How Often Should You Calibrate Your Toxic/Flammable Gas Detector?

Reprinted with permission from the United Electric Controls Blog.

When we think of gas detector calibration and how often it must be performed, it is dependent on many variables. First and foremost is determining if a gas sensor is out of calibration.

The best way to establish this is through a “bump” or functional test using a certified standard gas mixture of known concentration. If the device is functioning properly and still measuring gas within tolerance, calibration is unnecessary. Bump testing should be performed as regular maintenance on any gas detector. With the frequency depending on the sensor technology, manufacturer recommendations, specific company standard operating procedures and environment.

The two most common sensor types are NDIR and Electrochemical.

NDIR sensors tend not to drift and are calibrated prior to shipment. They require a bump testing frequency of 6 months or less to ensure performance is consistent. Calibration is only necessary if bump testing indicates the sensor is out of specification. Electrochemical sensors tend to drift over time and require bump testing every 3 to 6 months. Calibration is recommended annually or if bump testing indicates an out of spec sensor.

Due to the technology of electrochemical sensors, they will deplete over time and more rapidly if exposed to the target gas. They can also be poisoned if exposed to certain gases. If this is a risk, then bump testing more frequently is prudent. Calibration frequency can also be dependent on gas detector relevance. If it is a portable device, then it is pragmatic to bench calibrate before utilizing it in the field. If an area is planned to have significant traffic or work, then calibration should be performed for this event.

The sensor technology industry is constantly evolving, and with that newer sensors are assuring longer periods between calibration, or potentially no need to calibrate at all.

Using newly developed materials and software, sensors may last thousands of cycles without any performance decay, even if exposed to extreme environments or chemicals. The future is markedly promising.

Remember, the most important reason to calibrate your Vanguard Gas Detector is to provide accurate gas concentration readings in order that it could prevent illness, injury or death to personnel in the area. Your Vanguard may be exposed to extreme environments such as high or low temperatures, high or low humidity, or even harsh chemicals that may require more frequent calibration.  With proper maintenance, your Vanguard can provide the safety your team deserves.
