CONTROL VALVES ONLINE Independent Authorized Bonomi North America stocking distributor

INTRODUCTION

Considerations for media, pressure, flow, and temperature should be made prior to valve installation, as well as the conditions for pipe line expansion and contraction. When choosing valves, proper sizing, seat, stem, and body materials will greatly increase performance and reduce the chance of failure. Properly installed in piping systems, Bonomi ball valves are suitable for applications including potable water (Lead Free valves), hot water, gas, steam, oil, and vacuum.

 OVERALL WARNING

Before installation and before performing any maintenance, to avoid personal injury to yourself, fellow workers, or damage to property from release of process fluid, please take the following steps:

  1. Shut off all operating lines to the valve site.
  2. Isolate the valve site from the line fluid.
  3. Release process pressure.
  4. Drain the process fluid from the valve site.

 PRELIMINARY CHECKS

  1. Before installing the valve, check the body valve and associated equipment for any damage that may have occurred because of the shipping or storage.
  2. Prior to installation, inspect the pipeline and the mating pipe making sure both are free of foreign material. In addition, inspect these piping components ensuring they are clean, and there are zero burrs or pits that could cause leakage.
  3. The pipe/valve assembly must be free of tension before and after installation. Neither valve nor copper tubing is to be used as a means of support.
  4. The valve should be manually cycled a couple of times prior to installation.
  5. Make sure the valve is installed in the OPEN position.
  6. Brass ball valves are NOT to be installed at or BELOW GROUND LEVEL.
  7. Bronze ball valves can be installed at or below ground level, but NOT BURIED.
  8. Under no circumstances the valve should be used as a grounding electrode for electrical systems
  9. Inspection, testing, insulation and purging of the installation shall be performed using applicable local codes
  10. Please remember to separate the product and packaging materials (e.g. paper, metal, plastic, non-ferrous metals) and dispose in accordance with all national, state and regional requirements.

 THREADED ENDS

Unless otherwise specified, ball valve pipe threads are American National Standard Taper Pipe Threads [NPT] to ANSI/ASME B1.20.1.

All pipe and valve connections should be free of dirt, grease, and metal. Unclean pipe/valve connections are the number one cause of connection leakage.

Proper connection and thread seal is generally made by the use of any Teflon™ products, including PTFE formulated pipe compound. Teflon pipe compound is recommended on all pipe installations that are not Teflon-restricted applications because of the excellent sealing capabilities at all temperatures and pressures of threaded brass ball valves. Do not use Teflon in applications restricting its use (oxygen, tobacco, etc.). All pipe-joint tape and compounds must be non-toxic, NSF/UPC listed to maintain certifications (UL157). Be sure to apply enough sealant to fill the first 3 to 4 threads, as the screwing action will move the sealant up and around the threads.

Brass and bronze are soft metals. When using a bench vice to hold the valve, be aware that excessive pressure can deform and damage the valve body.
