Gate valves are bi-directional and can be installed in any position. However, the preferred orientation is
with the stem pointing vertically upwards.

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.


  1. Handle with care. DO NOT weld the flanges to the piping after installing the valve
  2. Water hammers might cause damage and ruptures. Inclination, twisting and misalignments of the piping
    may subject the valve to stress, once installed. It is recommended that elastic joints be used in order to
    reduce these effects as much as possible. The disc must be partially open. The mounting can be made
    with the stem axis in a horizontal or vertical position.
  3. Verify maximum working pressure and limits of use. Place the valve between two flanges. While placing
    the valve, ensure there is sufficient space in order not to damage the rubber. Do not mount seals
    between valve and flanges.
  4. Carefully clean the contact surface. DO NOT weld the flanges to the tube if the valve has already been
  5. Tighten the bolts crosswise and progressively, in order to distribute the pressure equally before the body
    and flanges come into contact with each other
  6. Turbulences of the fluid might increase erosion and reduce the life-cycle of the valve. Install the valve at a
    distance of at least 1 x DN upstream, and at a distance of 2-3 x DN downstream, away from fittings or
    bends. Check that no other components of the piping interfere or create damage or malfunctioning. If
    they do, a spacer should be inserted for the valve to operate correctly.


For valve operating with hazardous liquids(toxic, corrosive…) , if there is a possibility of residue remaining in
the valve, take due safety precaution and carry out required cleaning operation. Personnel in charge must
be trained and equipped with appropriate protection devices.
Prior to disposal, disassemble the valve and separate the component according to various materials. Please
refer to product literature for more information. Forward sorted material to recycling (e.g. metallic materials)
or dispose it, according to local and currently valid legislation taking into consideration the environment.
