Project Description



Shut-off ball valve split-body type made of ductile iron with floating ball, manufactured according to the relevant product standards.
Suitable for GAS. Well indicated: for installation in line and end of line, for services with frequent activations.
The 160 ball valves is a full and straight bore, which reduces turbulences and minimizing head loss.
Inner and outer epoxy coating, high temperature resistant. Environmentally friendly water-based paint, RAL 5002.

160: Cast iron, flanged

Keep in a dry and closed environment.
While stored, the valve must be fully open to avoid any damage to the seats.


  1. Handle with care. The valve must be installed in either the ON or OFF position.
  2. Place the valve between the flanges of the pipe and install the seal between the pipe and valve flanges. Check the correct position of the seals.
  3. The distance between the counter flanges should be equal to the valve’s face to face distance. Do not useR bolts of the counter flanges to bring the piping close to the valve. The bolts should be cross tightened.
  4. Do not weld the flanges to the piping after installing the valve.
  5. Water hammers might cause damage and ruptures. Inclinations, torsions and misalignments of the piping may subject the installed valve to excessive stresses. It is recommended that elastic joints be used in order to reduce such effects as much as possible.
  6. While heating from room temperature to the high operating temperature, the liquid located between the body and ball (valve open), or located in the bore of the ball (valve closed) tends to expand and may damage the ball and the seats; it is recommended to open and close the valve at intermediate temperatures during the heating process (for example, at 40°C /60°C/…).
  7. At below zero temperatures, the liquid between the body and ball may freeze, causing irreparable damage. If the valve is exposed to such conditions, insulation of the valve is recommended.
  8. It is recommended to operate the valve periodically, to prevent the build-up of materials on the ball and the seats, particularly in the presence of limestone.


  1. It is recommended that to replace the rubber O-rings at least every 24 months, and the PTFE seats, at least every 48 months. The period of replacement depends on the use of the valve.
  2. Clean the surface of the valve periodically, in order to prevent the accumulation of dust.

Before carrying out maintenance, or dismantling the valve, be sure that the pipes, valves and liquids have cooled down, that the pressure has decreased and that the lines and pipes have been drained in case of toxic, corrosive, inflammable or caustic liquids.
Temperatures above 50°C and below 0°C might cause damage to people.
