Spirax Sarco DCV3

Check Valve

Spirax Sarco DCV3 and DCV3LT valves are designed for installation between flanges. These valves can be used with media such as hot water, steam, condensate, and gases.
Flange faces comply with EN 558 Part 1, Series 49.

The standard valves (seat/disc - metal/metal) are designed for use with steam. For applications with mineral oil, compressed air, gas, and water, valves with a soft disc ring are recommended. DCV3 LT valves are designed for use at low temperatures.

Options

• Reinforced spring (opening pressure 700 mbar, only for DN15 - DN65 valves).
• With a Viton disc ring (for oil, compressed air, and gases).
• With an EPDM disc ring (for water).

Characteristics:

• DCV3LT can be used at temperatures down to -60°C, while the DCV3 can be used down to -10°C.
• DCV3 with high-temperature springs or the DCV3/DCV3LT without springs can be used in specific applications.
• The operating range of products with different seat materials (Viton and EPDM seats) is limited by the seat material.
• Parameters related to the valve body design level (PMA - maximum allowable pressure, TMA - maximum allowable temperature, etc.) and different spring types correspond to different operating pressures and temperatures.
• Designed for a maximum cold hydraulic test pressure of 60 bar g.
