The opening and closing part is a ball with circular through hole, the ball of lined valve rotates around the center line of the valve body with the stem to realize valve opening and closing. Stainless steel lined PFA ball valve made by special molding process offers good sealing surface and can achieve leakage-free use together with V-shaped PTFE packing. Manual PFA lined ball valve ball is cast as one part with valve stem, which eliminates the possibility of the valve stem bursting out of the pressure member due to pressure change to guarantees the safety.

PERFECT provides a complete line of stainless steel valve for sale that is supplied to various industries. Our lined ball valves are lined with perfluoroethylene(PFA) and suitable for the working environment with strong corrosion resistant media range up to DN300. We are a fully stocked manufacturer and distributor of stainless steel lined valve and we make the valve easy to find for your need. We can also accept the OEM design whether you need special valves or have a large order to place. Please review the charts below for available sizes & pressure & material or fill the contact form below.

  • Design with stainless steel body and PFA lining offers high chemical stability, suitable for any highly corrosive chemical medium;
  • Full bore, floating ball and side entry design making the valve closed without leakage in the whole pressure range, which is convenient for cleaning and maintenance of the pipeline system;
  • Opening and closing parts casting (forging) with valve stem to avoid the possibility of the valve stem out of pressure parts caused by pressure change, ensured the safety of engineering;
  • Compact structure and double D stem head reduced media retention, high performance HYPATITE PTFE ball seat and ring shaped PTFE packing,making the valve leakage free;
  • Two piece, three pieces flanged lined ball valve can be applied to a variety of requirements for pipeline system and operating conditions, three-piece ball valve allows the main valve body split with two sides of the body separation, convenience for online replacement and maintenance.
