STEM WITH ANTISTATIC DEVICE

Fire-safe valves are provided with antistatic stem as standard. In some applications, when explosive or Flammable fluids are handle, electric charges producing Sparks are imminent which, in turn, can induce accidents. The antistatic device maintains permanente contact between body, stem, and ball all time avoiding electric charges caused by friction while operating the valve. Note: […]

SPHERE OF RELIEF

The design of  WORCESTER® / RHINO VALVES WORLDWIDE®´s  cryogenic (all Models) ball valves assures thet the relief hole of the ball ( Wich needs to be palced in the downstrem direction) avoids an increase of pressure caused by the flash due to the concentration of fluids in the interior. This assures that the valve will […]
