Threaded Spring Safety Valves VYC 095

 

Threaded Spring Safety Valves VYC 095 are safety valves designed for pressure relief in various systems. These valves operate automatically, opening proportionally to pressure increases, thus preventing overpressure situations.

 

Specifications:

 

 

  • Inlet/Outlet: Male BSP inlet with a female outlet.

 

 

  • Material Options: Available in brass, brass with stainless steel components, and full stainless steel.

 

 

  • Maximum Temperature: 260°C.

 

 

  • Maximum Pressure: 25 bar, with mixed construction available for pressures above 16 bar.

 

 

  • Application: Suitable for both gases and liquids.

 

 

The VYC 095 type comes in two models: AP and ES.

 

 

They are essential components in systems that require precise pressure control, ensuring both safety and system functionality

I  – Saturated steam in kg/h.

II  – Air at 0°C and 1,013 bar in [Nm3/h].

III  – Water at 20°C in l/h.

 For other, not so dense liquids, other than water at 20°C apply:

 

VL =                 A • VA Ó VA = VL •                         L

L                                     A

 VA = Water flow according to table.

VL = Liquid flow.

A = Water density at a 20°C. ( A =998 kg/m³)

L = Liquid density.
