Generant’s ordering documentation confirms that SS = 316 stainless steel, B = Buna-N, 500 = 1/2″ NPT, and 1 = nominal 1 PSIG cracking pressure. For the 1/2″ CV size, Generant publishes a 7.4 Cv, 150 SCFM at 5 PSID, 2.93″ overall length and 1-1/2″ hex.
GENERANT CV-500SS-B-1 1/2″ 316 Stainless Steel Inline Check Valve – Buna-N – 1 PSIG
Genuine Generant CV-500SS-B-1 industrial inline check valve designed to allow flow in one direction while preventing reverse flow.
This configuration features a rugged 316 stainless-steel body, 1/2″ female NPT inlet and outlet connections, Buna-N seals, and a 1 PSIG nominal cracking pressure. Generant specifies Buna-N for an operating temperature range of approximately -40°F to 250°F (-40°C to 121°C).
Generant’s CV Series uses a fully guided poppet with a free-floating O-ring design. Metal-to-metal positive stops protect the O-ring and spring from overstress, while the design provides high flow with relatively low pressure drop.
For the 1/2″ size, manufacturer data specifies a Cv of 7.4, approximately 150 SCFM at 5 PSID, an overall length of approximately 2.93″, and a 1-1/2″ hex.
Key
316 stainless-steel construction; 1/2″ FNPT connections; Buna-N seals; 1 PSIG nominal cracking pressure; high-flow design; 7.4 Cv; fully guided poppet; one-way flow control; 100% factory tested for backflow leakage.
Important: Unlike the “-X” oxygen-cleaned Generant valves you’ve been listing, the supplied part number CV-500SS-B-1 does not specify oxygen cleaning, so I would not advertise this particular valve as O2 cleaned unless the packaging, certification, or valve documentation specifically confirms it.
Condition: If unused surplus, use New – Other / New Old Stock and note that packaging may have shelf/storage wear. Buyer should verify the exact part number, seal/media compatibility, pressure requirements, and connection size before installation.
