Isolation Valves

  • While gate valves have historically been used in isolation applications, there are a few reasons why the 33000 series is the preferred option. And with the 33000 available in Double Flanged Long Pattern configurations, customers can replace gate valves with the ease. The Masoneilan 33000 Triple Offset Butterfly Valve is a robust triple offset butterfly valve that offers customers true zero leakage capability, with compliance to API 598. With its patented design, the 33000 offers customers a unique solution in isolation applications that competing valves cannot match.

    • Smaller in size and weighs less
    • Better seat leakage results (33000 offers true zero leakage)
    • Eliminates rubbing of wear components due to triple offset cam action
    • Cost effective

    By being able to offer true leakage results, ease of maintenance and dependable performance, the 33000 Masoneilan Triple Offset Butterfly valve is the preferred choice for isolation applications.

    Available in 3" to 48", 150CL to 600CL, a variety of end connections and materials along with cryogenic configurations, the 33K can fit almost any application. By the end of the year the full product offering will be available in ValSpeQ for sizing and quotation.
