Key spec means
-
“PN16” means the valve is rated for a nominal pressure of 16 bar (1.6 MPa) under the specified standard.
-
“Flanged” indicates the end‐connections are flanges (rather than socket/weld) for bolted flange installation.
-
“RSV” stands for Resilient Seated Valve (a resilient‐seal gate valve) — the gate is rubber-encapsulated (typically EPDM) for a tight shut-off. For example, the material list shows: “Gate SG Iron EPDM Encapsulated”. SANSPAR+2EPNS+2
-
The “SABS 664” or “SANS 664” (in South Africa) refers to the specification/standard for resilient seated gate valves. For instance: “Flanged RSV Gate Valve – PN16 – SABS 664.” Hydrocon+2EPNS+2
-
The mention of “LHC or RHC” refers to Left Hand Close or Right Hand Close (i.e., the direction in which the handwheel or cap/top must be turned to close the valve). Many suppliers mention “Right hand or left hand closing” as an option.
- 150 mm RSV
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).
