Industrial Valve Types & Applications
Industrial valves control the flow, pressure, and direction of liquids, gases, and slurries within complex piping systems. At Surplusfishervalves, we specialize in providing a wide range of valve types, each engineered for specific operational parameters and process requirements.
- Gate Valves: Designed for on/off control with minimal pressure drop. Ideal for isolation services in oil & gas pipelines and water utilities.
- Globe Valves: Offer precise throttling control, commonly used in chemical plants and power stations for flow regulation.
- Ball Valves: Provide quick quarter-turn shutoff with tight sealing. Widely utilized in petrochemical and refinery applications.
- Butterfly Valves: Compact and lightweight, suitable for large diameter pipelines in HVAC, wastewater, and industrial cooling systems.
- Check Valves: Ensure unidirectional flow, prevent backflow, and protect pumps and compressors.
- Plug Valves: Used for on/off service and flow diversion in high-pressure hydrocarbon processing.
Each valve type is manufactured with varying pressure classes, end connections, and actuator options to meet precise operational needs.
Material Specifications & Grades
The selection of valve body and trim materials is pivotal to durability, corrosion resistance, temperature tolerance, and compliance with industry standards. Surplusfishervalves stocks valves fabricated from the following common material grades:
| Material | ASTM/ASME Grades | Typical Applications | Corrosion Resistance | Temperature Range | Mechanical Strength |
|---|---|---|---|---|---|
| Carbon Steel | ASTM A216 WCB, A105 | General service, steam, water, oil pipelines | Moderate; requires coatings in corrosive environments | -29°C to 425°C | High tensile and yield strength |
| Stainless Steel | ASTM A351 CF8, CF8M (304/316) | Chemical processing, food & beverage, pharmaceutical | Excellent; resistant to oxidation and chemical attack | -196°C to 870°C (depending on grade) | Good mechanical properties with excellent ductility |
| Alloy Steel | ASTM A217 WC6, WC9 (Chromium-Molybdenum) | High temperature steam, power plants, petrochemical | Good; enhanced creep and oxidation resistance | 400°C to 650°C | Superior strength at elevated temperatures |
| Ductile Iron | ASTM A536 Grade 65-45-12 | Water distribution, wastewater treatment | Moderate; prone to corrosion without lining | -40°C to 150°C | High tensile strength with flexibility |
| Bronze/Monel | ASTM B148 (Bronze), ASTM B164 (Monel) | Marine, saltwater, chemical resistant applications | Excellent; highly resistant to seawater corrosion | -50°C to 300°C | Good strength with excellent corrosion resistance |
Valve trim materials (seats, discs, stems) are similarly selected based on media compatibility and wear resistance, including hardened stainless steels, inconel, and stellite overlays for high-wear environments.
Compliance & Regulatory Certifications
Compliance with industry standards and regulatory requirements is non-negotiable when procuring valves for industrial use. Surplusfishervalves rigorously verifies the certification and traceability of every valve in our inventory, ensuring adherence to applicable codes such as:
- API (American Petroleum Institute) Standards: API 6D for pipeline valves, API 600 for steel gate valves, API 608 for metal ball valves, etc.
- ASME (American Society of Mechanical Engineers) Boiler & Pressure Vessel Code: Section VIII compliance for pressure containment.
- ISO Certifications: ISO 9001 for quality management systems, ISO 5211 for valve mounting flange standards.
- NACE MR0175/ISO 15156: Material requirements for resistance to sulfide stress cracking in oilfield equipment.
- Fire-Safe Certification: API 607 or ISO 10497 certified valves for fire-safe performance.
- Pressure Equipment Directive (PED): For valves supplied to European markets.
All valves supplied by Surplusfishervalves come with comprehensive mill test reports (MTRs), material traceability documentation, and where applicable, third-party inspection certificates to facilitate seamless QA/QC and regulatory audits.

Frequently Asked Questions
1. How does Surplusfishervalves ensure the quality and reliability of surplus industrial valves?
At Surplusfishervalves, every surplus valve undergoes a rigorous multi-step inspection and testing process, including dimensional verification, pressure testing per API standards, non-destructive examination (NDE) such as dye penetrant or ultrasonic testing, and material verification via mill test reports (MTRs). We also perform operational checks on actuators and seals to confirm full functionality. Any valve failing to meet our stringent quality parameters is either reconditioned by certified technicians or excluded from inventory. This process guarantees that our surplus valves perform comparably to new equipment while offering cost efficiencies.
2. What certifications and documentation are provided with valve purchases?
We supply comprehensive certification packages including mill test reports (MTRs) confirming chemical and mechanical properties, API or ASME compliance documentation, third-party inspection certificates (if requested), and test certificates for hydrostatic or pneumatic pressure testing. Our documentation supports your internal QA/QC protocols and regulatory audits, ensuring full traceability from raw material to finished product.
3. Can Surplusfishervalves supply valves for hazardous or high-temperature applications?
Yes. We stock valves constructed from alloy steels such as ASTM A217 WC6/WC9 and stainless steel grades designed for elevated temperature and corrosive environments. Additionally, fire-safe certified valves (API 607/ISO 10497) are available for critical safety applications. Our team can assist you in selecting valves with appropriate pressure-temperature ratings, material compatibility, and certifications tailored to your hazardous service conditions.
4. What are the typical lead times for surplus valve orders?
One of the key advantages of purchasing surplus valves from Surplusfishervalves is immediate availability. Most valves in our extensive inventory are ready for shipment within 24-48 hours after order confirmation. For specially refurbished or customized valve solutions, lead times may extend to 1-2 weeks depending on scope. We prioritize rapid response and logistics support to minimize downtime for your projects.
5. How can I verify the compatibility of a valve with my existing system?
Our experienced engineering sales team provides detailed technical assistance to match valve specifications with your process requirements. We review key parameters such as pressure class, end connections (flanged, butt weld, threaded), material compatibility with media, temperature range, and actuator type. We can also provide dimensional drawings and CAD models to ensure seamless integration. For complex applications, we recommend sharing P&IDs and process data sheets to facilitate precise valve selection.
