Straight-through sampling valves for representative sample extraction from process pipelines, reactors, and tanks in pharmaceutical, food, biotech, and cosmetic applications. Full-bore design with zero dead legs, zero pockets, and zero crevices meets 3-A Sanitary Standards and EHEDG Type EL Class I guidelines. SS316L body with mirror-finish electropolished surface (Ra <= 0.4 or 0.25 microns). Tri-clamp or butt weld ends. FDA-approved PTFE/EPDM/silicone seals. Pneumatic actuator option for automated CIP/SIP batch sampling. ASME BPE / 3-A SSI / FDA 21 CFR 177.2600 compliant.
Technical Specifications
| Parameter | Specification |
|---|
| Product Type | Sampling Valves |
| Category | Sanitary Valves |
| Size Range | 1/2" to 4" (DN15 to DN100) -- sample outlet: 1/4" to 1" tri-clamp or threaded NPT typical |
| Pressure Rating | PN10 / PN16 / Class 150 (low pressure typical for sanitary service) |
| End Connections | Tri-clamp (sanitary, standard) / Butt weld (sanitary, DIN 11850 / ISO 1127 / ASME BPE) / Threaded NPT / BSP (sample outlet) / Flanged RF (non-sanitary option) |
| Body Material | ASTM A351 CF3M (SS316L) -- low carbon for weldability and corrosion resistance / ASTM A351 CF8M (SS316) on request |
| Stem / Spindle Material | SS316L with Stellite 6 or chrome plating on tip / SS316L hardened tip |
| Seat Material | SS316L integral seat with mirror finish Ra <= 0.8 microns / EPDM or PTFE soft seat insert (on request for lower leakage) |
| Packing / Seal Material | PTFE V-ring (FDA-approved, -50 to +200 deg C) / EPDM (FDA-approved, -20 to +120 deg C) / Silicone (FDA-approved, -60 to +200 deg C) |
| Surface Finish | Ra <= 0.8 microns (standard) / Ra <= 0.4 microns (high purity, electropolished) / Ra <= 0.25 microns (ultra-high purity, electropolished + passivated) |
| Operation | Handwheel (standard) / Pneumatic actuator (spring-return, for automated CIP/SIP batch sampling) / Manual lever with locking device |
| Leakage Class | EHEDG Class I -- zero visible leakage; 3-A Sanitary Standard -- cleanability and drainability verified |
| Temperature Range | -20 deg C to +120 deg C (EPDM seal) -- up to +200 deg C (PTFE seal / SS316L body) |
Materials of Construction
| Component | Material |
|---|
| Stainless Steel 316L | ASTM A351 CF3M (SS316L) body, stem, and seat -- low carbon content prevents carbide precipitation during welding, maintaining corrosion resistance |
| Stainless Steel 316 | ASTM A351 CF8M (SS316) body on request for non-welded applications |
| Elastomer Seals | FDA-approved EPDM, PTFE, or silicone seals per 21 CFR 177.2600 |
Testing & Inspection
| Test | Requirement |
|---|
| Testing | Hydrostatic shell test 1.5 x WP per API 598 / EN 12266-1; Seat leakage test per API 598 / EN 12266-1; Functional test -- full stroke, torque; Material certificates per EN 10204 3.1 |
| Certification | ISO 9001:2015 QMS, EN 10204 3.1 material certificates, hydrostatic and seat test reports |
Applicable Standards
| Standard | Description |
|---|
| Design Standard | 3-A Sanitary Standards (3-A SSI), EHEDG Type EL Class I (on request), ASME BPE (reference), FDA 21 CFR 177.2600 (elastomers) |
Notes
- Pipeline size, sample outlet size, end connection type (tri-clamp / butt weld / threaded), and surface finish requirement must be specified by the purchaser.
- For aseptic / sterile applications (USP Class VI, EHEDG Class I), electropolished surface finish Ra <= 0.4 microns with full material traceability and certificates is required.
- For CIP/SIP automated sampling, specify pneumatic actuator air pressure, control signal (4-20 mA / digital), and integration with batch control system.
- All elastomer seals must be FDA-approved per 21 CFR 177.2600 and USP Class VI (on request for pharma); specify EPDM, PTFE, or silicone based on chemical compatibility.
- All valves are manufactured by Supreme Valves India as per our standard specifications.
