T85/99 – THREADED STRAIGHT THROUGH MODEL

Straight through Valve whose principal characteristic is its thread connection to the pipe. The Bonnet is the same as that of the straight through type (MODEL 85) for both manually driven and automatic valves. Due to the design of the body, these valves cannot be lined.

The main features of the valve:

  • Low cost maintenance .
  • Simple and reliable design
  • The maintenance is based on Installation of a new diaphragm. It  is accomplished by simply removing the bonnet bolts, lifting off the bonnet assembly, replacing the diaphragm, and reassembling. There is no need to remove body from the line.

*Valves manufactured following European Pressure Equipment Directive PED 97/23/CE* Válvulas fabricadas conforme a la Directiva Europea de Equipos a Presión PED 97/23/CE Seccion 3 articulo 3.
