New under the RASCO brand: PC ‒ RASKO ‒ N and PC ‒ RASKO ‒ M safety valves





We present to your attention a new development of RASKO NPF LLC - inexpensive and compact safety valves for protecting pressure gauges and pressure gauges from the negative impact of peak overloads: PK-RASKO-M at operating pressure from 0.4 to 6.0 MPa (from 4 to 60 kGf / cm2) and PK-RASKO-N at operating pressure from 4 to 40 kPa.


Safety valve PK-RASKO-M with pressure sensor and pressure gauge with a diameter of 100 mm


Safety valve PK-RASKO-N with head diameter 65 mm

The PK-RASKO-M and PK-RASKO-N valves are operable in the temperature range of -30 .... + 70 ° C. Work is underway to expand the specified temperature range. They can be used in liquid and gas systems using a wide variety of liquids and gases, non-corrosive to stainless and carbon steel, aluminum and copper alloys, fluoroplastic, silicone and rubber.

Distinctive features:

• Combination of pressure monitoring capability with overload protection.

• Wide range of tuning ranges.

• Extended range of connecting threads.

• Minimum weight and dimensions.

• Optimum price / quality ratio.

Recommended use cases:

  • in liquid systems - in the presence of the risk of water hammer due to the low compressibility of the liquid,
  • in gas systems - when installing pressure control devices after gas pressure regulators, where a high-pressure pulse passes to the output of the pressure regulator for a period of time until the regulator's regulator is in the position corresponding to the setting pressure, and also after the relay valves.

PK-M valves with similar technical characteristics are several times cheaper than foreign analogues, and PK-H valves do not currently have foreign or domestic analogues. Products fully comply with import substitution requirements.

In the coming months, we are ready to supply PK-M and PK-N valves for your orders, operating in the range of ambient temperatures of -30 .... + 70 ° C. Work is underway to expand the specified temperature range.
