Functional Requirements

  • Standard piping configurations are made to the inlet of the valve by connecting via the 3/8” BSP /NPT Female thread. The piping connections to the outlet of the valve are made via a the 3/8” BSP /NPT Female thread
  • This valve has been specifically designed  for Natural , manufactured, Mixed LP and LP / air mixtures.
  • Standard electrical connections are made through the following options
    • via the two 6.3mm tabs protruding from the valve. It is advisable to ensure that the electrical receptacles connecting the tabs are insulated.
    • Though single or double insulated leads. The leads are 0.75mm 2 tin plated conductors.
    • Standard lead length is 200mm, however any specific customer requirement can be met.
    • Through DIN 43650 Form A / ISO 4400, EN175301 – 803:2000 specification

Ambient Conditions

The valve will operate correctly within the following temperature conditions;

  • Ambient temperature: -40° C to 135° C
  • Relative humidity: 0% to 95%

Valve Performance  

Valve Capacity

120,000 BTU/Hr

Resistance to bursting pressure

Minimum static bursting pressure > 6.5 Mpa (65 bar), reached through a gradual pressure increase spread over 20 seconds starting from atmospheric pressure.

 Strength of coupling thread

With a minimum of 5 full threads engaged, the inlet and outlet coupling threads do not strip or break when subjected to a tightening torque of 50Nm.

Corrosion resistance of stainless steels

The stainless steels pass the salt spray fog test according to ASTM B 117 salt spray fog test. Stay time 100 hours. After having been dried in ambient temperatures, there are no rust spots present. A small yellow discolouration is acceptable.

 Solenoid resistance to fire

Solenoid coil former and encapsulant are rated to UL94 – V0 and/or Glow wire-        
IEC 695-2-1, 960° C

Resistance to arc tracking / earth leakage

Solenoid assemblies are flash tested to 3.3 – 3.5kV ac, 50 Hz between earthed parts and live parts of opposite polarity.

Operating pressure range

The valve operates correctly between 0 Kpa and 6kPa  at the inlet of the valve.

 Opening pressure drop

The valve is designed to comply with IEC730-2-8 clause 18.101.3

 Opening Response Time

Flow established within 0.5 sec of power application

 Closing Response Time

Within 0.5 sec after power is removed
