​RF Gate Valve

Product Details

RF end forged steel gate valves are ideal for high-pressure steam, catalytic reformers, hydrocrackers, and other tough services.

● Stronger, leakproof bolted body bonnet joint ensures joint tightness with a higher bolting torque.
● Wedge guiding minimizes seat rubbing and scuffing resulting in long cycle life.
● Designed to ASME B16.34.
● Body made of superior strength forgings and optional cast steel.
● stem seal offers tight seal with little to no maintenance over long periods of time.
● Optional live-loading of packing and leak off.
● Non-rotating stem.
● Hardfaced seating faces resist erosion.
● Available with provision for seal weld.
● Other sizes and pressure classes available. Contact the company for specifications.
