Deskripsi Produk

The Fisher V250 is a heavy-duty, flangeless throttling ball valve designed for flow control in gas transmission pipelines, gas distribution systems, and liquid pipelines. It offers three sealing configurations—single ball seal, flow ring seal, and dual-seal construction—to meet various operational requirements. Suitable for high-pressure, high-flow, and demanding media applications, it provides precise throttling performance, while its compact flangeless design makes it ideal for space-constrained piping systems.

Fitur

• The valve’s tapered-polygon ball-to-shaft connection and clamped splined actuator linkage work together to eliminate any lost motion or deadband in the drive train, ensuring precise and responsive control performance.

• Featuring a reduced ball port design, the valve delivers a modified equal percentage flow characteristic that provides excellent throttling control across various flow conditions.

• For challenging sour service applications, the valve offers material options that fully comply with NACE MR0175-2002 requirements, making it suitable for handling corrosive environments.

• Its pressure-balanced drive shaft incorporates PTFE-lined bearings and a pressure-assisted sealing arrangement, significantly extending the valve’s service life while maintaining reliable operation.

• The innovative two-piece ball and shaft assembly design simplifies maintenance by allowing complete trim overhaul with minimal parts replacement, reducing downtime and service costs.

• An optional live-loaded packing system is available, featuring ultra-smooth shaft surfaces and dynamic loading to ensure superior sealing performance in demanding operating conditions.
