Description

The Low Temperature Steel Globe Valve is built from LCB low-temperature carbon steel with an extended bonnet that keeps the packing area away from the cold medium. It provides reliable shut-off and throttling in cryogenic and low-temperature service such as LPG, liquid ammonia and refrigerated gas lines.

Technical Specifications:
  • Pressure Class: PN16 / PN25 / PN40 / PN64
  • Size Range: DN15 – DN300
  • Applicable Medium: LPG, liquid ammonia, ethylene, low-temperature gases and liquids
  • Operating Temperature: -46°C to 150°C

Key Product Features:
  1. Low-Temperature Material: LCB steel keeps its toughness down to -46°C.
  2. Extended Bonnet: Protects the stem packing from freezing.
  3. Tight Shut-Off: Stainless sealing faces for reliable closing.
  4. Throttling Capability: Good flow regulation characteristics.
  5. Impact Tested: Materials tested for low-temperature service.
Applications:

Ideal for LPG Storage & Transfer, Refrigeration Plants, Chemical & Fertilizer Plants, and Gas Processing. Specifically suited for cold media that would make ordinary carbon steel brittle.
