PN16 Flanged 665 RS

• Key Specifications & Features

  • It is a rising-spindle (RS) design (i.e., the stem visibly rises and falls during operation), as indicated by the “665” / “RS” designation. epns.co.za+3katlehowater.co.za+3epns.co.za+3

  • Rated for PN16 (nominal pressure 16 bar) for the “665” version. KLINGER Mzansi+3epns.co.za+3Macneil Steel & Valves (PTY) Ltd+3

  • Flanged ends (i.e., the valve has flange end connections, rather than socket weld or threaded). epns.co.za+1

  • Body material: Ductile Iron (SG Iron / GGG40) (for many RSV valves) with fusion bonded epoxy coating inside & out. SANSPAR+2Major Valves+2

  • Sealing: Resilient-seated gate (i.e., a rubber or elastomer-sealed wedge/disc – e.g., EPDM encapsulated) for tight shut-off. SANSPAR+1

  • Suitable for water / neutral liquids, municipal / industrial reticulation. For example “above ground installation … waterworks, wastewater management” for rising spindle gate valve of 665 type. woodlandsfire.co.za+1

  • Visual position indicator: because the spindle rises, you can see whether the valve is open or closed.

Suitability & applications

Given the specifications, this type of valve is suited for:

• Water distribution, municipal networks, reticulation, general service isolation valves (rather than high‐pressure or steam duties unless specified).

• Low to medium pressure systems (up to 16 bar) in line with the PN16 rating.

• Situations where a tight shut‐off is needed (thanks to the resilient seat) and relatively low operating torque helps.

• Environments where corrosion protection is required (epoxy coating, protected materials).

• Systems where either left‐hand or right‐hand closing is required (important for orientation/installation).
