Condensate drains remove condensate separated in centrifugal separators, air receivers, refrigeration dryers and filters from the compressed air system. Wherein the spherical valve body has a slot passage around a portion of a circumference thereof, such that when the valve body is in the first position the slot passage couples the input port to the condensate collection port, and when the valve body is in the second position the slot passage couples the condensate collection port to the drain port.
Designed to fulfil your specific requirements, the robust, volume-controlled condensate drain is designed and built as a hard-coated version or as stainless steel. The ball need only condensate drain valve turn 90 degrees to go from inlet to drain functions. A-17 b show an embodiment of the invention using a double-slotted ball in the collect” and drain” positions, respectively.

It will be understood that while the various embodiments of the invention have been described primarily in terms of condensate collection from pressurized fire protection systems, and more generally for draining condensate in gas-pressurized piping systems, the invention has applicability to other pressurized systems as well where it is desirable to extract a fluid from a pressurized line without connecting the pressurized line to the destination of the extracted fluid.
The seats for the Double L” flow control element should have sealing faces that are at least as wide as the diameter of the corresponding port in the flow control element—ultra-high molecular weight polyethylene (UHMWPL) is a possible material for the seals.

The problem with non-rising stem (NRS) valves is that they don't provide an external indication of where the gate is. Rising stem and OS&Y (Outside Screw & Yoke) valves do provide external indication of gate position by virtue of the fact that the external stem movement mimics the internal gate movement.
The different series of condensate drains are each geared toward different applications or modes of operation. No. 5,687,755 Equipment Comprising a Condensate Trap” define valves which redirect flow. Learn about our development from a machine shop to one of the world's most successful manufacturers of compressed air systems.
Alternatively, the actuator may powered by a motor, solenoid, ram or other kind of actuator which can move the valve from collect” to drain” to perform the drain function in response to an electrical, hydraulic or pneumatic control signal. As used herein, the term ‘integral' means a part of or attached to the valve case while the valve is in use, even though the collection chamber may be removable for assembly or maintenance or other reasons.
