Chemical Trim API Load/Unload Valve - API496C

The API496C is a Chemical Trim (FFKM) API Adaptor that conforms to API RP1004. It has been designed to be compatible with various chemicals, engineered to offer quality bottom loading through excellent performance and maximum safety and is supplied with a drain plug (1/2” BSPT), sightglass and sightglass blanking plate.

FFKM (a perfluoroelastomer commonly known as Ekraz or Kalrez) is one of the most chemically resistant materials available and is suitable for some of the harshest chemical compounds. FFKM is commonly used with aggressive, corrosive and reactive chemicals.

Features & Benefits
  • Complies to API RP1004 – compatible with all API couplers.
  • Ease of maintenance for reduced downtime.
  • Set of mounts to match industry standard air interlock valves such as the Liquip AIV3.
  • The bulk of internal components are stainless steel for increased strength and product service life.
  • Ergonomically designed handle.
  • Lightweight design – 4.8kg
  • Borosilicate sightglass to visually check for retained product (Blank plate also provided).
  • Flange is gramophone finish for improved sealing.
  • 100mm bore all through for minimum pressure drop.

FFKM Seals

-Aluminium body, nosecone and poppet.
-Stainless steel shaft, cam & roller.
-Perfluroelastomer (FFKM) main product seals.
-Teflon poppet bush.

Poppet Travel

The spring loaded poppet can be opened by the handle for discharge, or by an API coupler for bottom loading or unloading. For safety, the handle does not move when a coupler actuates the poppet. The handle is a “pull up-to-open” design, which when used rotates an internal cam to open the poppet. The cam uses the over-centre principle to hold poppet in its open position while unloading. Dual o-ring seals on shaft prevent leaks.

Electrical continuity guaranteed by use of non-anodised nose cone.

Flange is 100mm TTMA standard. Mount so that when viewed from the front, the handle is on the right hand side and pointing down.
