K31 K32 K33 Series Dome Loaded Pressure Regulator

K30 Series Dome Loaded Pressure Regulators offer excellent pressure control at low to medium delivery pressures. Below 5 barg, the build standard is adjusted to increase sensitivity offering improved pressure control and flow performance. Its heavy duty construction makes the K30 Series ideal for arduous conditions and harsh environments.

Applications:

• Medium to Low Pressure Gas Supply Applications
• Liquid Pressure Control

Applications

Medium: Liquid and gases

Maximum inlet pressure:

• K31 & K32: 70 barg (1015 psi)
• K33: 55 barg (798 psi)

Outlet pressure range:

• K31 & K32: 0,5 … 70 barg (7,3 … 1015 psi)
• K33: 0,5 … 42 barg (7,3 … 609 psi)

Low pressure version: Inlet pressure: 25 barg (363 psi) Outlet pressure:

0,1 … 5 barg (1,4 … 73 psi)

Dome loading:

Internal or external via G1/4 connection. Domes should be loaded with air or inert gas.

Leakage:

Bubble tight (standard, typically 10-6 mbar l/s) Helium leak tested to 10-8 mbar l/s (on request)

Ambient/Media temperature:b> Elastomers:

• NBR: –10 … +100°C (+14 … +212°F)
• FPM: –20 … +150°C (–4 … +302°F)
• EPDM: –30 … +115°C (–22 … +239°F)

Body’s:

• Nodular iron –20 … +150°C (–4 … +302°F)
• Stainless Steel –40 … +150°C (–40 … +302°F)

External Sensing: For increased flow capacity at low delivery pressure, the K30 Series can be ordered with external sensing. This feature can be applied retrospectively to regulators already in the field providing an external sensing port has been machined into the body.
