Flowserve has announced the launch of the Valtek Valdisk high-performance butterfly control valve, engineered for high capacity and low-pressure loss. The valve is ideal for high-cycle applications that require a durable control valve solution capable of delivering reliable control and throttling accuracy. The Valdisk control valve is designed to provide long-lasting, bubble-tight shutoff in a variety of oil and gas and chemical applications, including pressure swing adsorption (PSA), air separation, chemical refining and others.
The valve is compatible with a range of actuators and is available in multiple configurations, including cryogenic, flangeless and double-flanged, to meet a variety of needs.
The Valdisk control valve has a high-thrust cylinder actuator coupled with an eccentric-cammed disc, which enables unmatched, high-performance throttling. The soft seat provides tight shutoff in both flow directions. This improves leakage resistance and uptime. A single pivot-point, splined shaft minimizes lost motion between the shaft and actuator, resulting in greater throttling accuracy. The double-offset disc design minimizes seat and disc wear as well as leakage, which extends seat life and minimizes maintenance costs.
