    Description

    Manual needle valves

    Needle valves offer maximum safety and reliability in handling flow, even in harsh operating conditions. These valves can be used bidirectionally and effectively isolate both liquids and gases. The heart of the valve is the specially shaped seat and the two-piece non-rotating stem. The longevity and reliability of these valves are ensured because the stem cannot lock against the seat. The pressure-containing parts are made of high-quality corrosion-resistant stainless steel. Reliability is documented through traceability, as each valve body includes references to trace its origin in case of issues. Medium-pressure (MP) and high-pressure (HP) valves come complete with collars and glands.

     

    Actuated needle valves

    High-pressure circuits can be automated using pneumatic actuated needle valves. The valve bodies and sealing system are identical to those of manual needle valves and offer the same advantages.

    Actuated needle valves are available in the following versions: NC (normally closed), NO (normally open), and DA (double-acting).

    HIP needle valves are an advanced solution thanks to the use of special materials such as Nitronic 50 for the stem, which helps limit hydrogen embrittlement and makes them more reliable and long-lasting. The seals are also designed to withstand temperatures as low as -40 °C. 

    As they feature no electrical components on the valve body, HIP valves are intrinsically safe for ATEX IIC zones and do not require flameproof enclosures. The valves and fittings (made of 316L stainless steel) are available in a range of sizes from 1/4" to 1".

    Ball valves come in two types of connections: NPT and MP/HP coned and threaded. Additionally, this type of valve is available with electric or pneumatic actuators.

    The available materials include:

    • Body/Side Adapter/Trunnion: Cold-316 cold worked stainless steel.
    • Packing: O-ring with PEEK backup ring.
    • Seals: Viton
    • Bearings: PEEK

    HIP ball valves with 1/4", 3/8" and 1/2" orifice and 1/4, 3/8, 9/16, 3/4 and 1" MP end connections offer reliable operation with no need for periodic adjustments.

    Thanks to the stem design and Trunnion technology , these valves ensure precise alignment and a perfect seal, with gaskets engineered for long-lasting performance.
