( Brand: Marlin Valve Co ), ( Manufacturer Part Number: A-2-150 ), ( Part Type: Check ), ( Valve Operation: Spring )
Review MARLIN VALVE CO Co. As is Butterfly Check 235 Psi 150 Lb Inch Ssvsr
The **Marlin Valve A-2-150 AS-IS Butterfly Check Valve (Model 235-150-SSVSR)** is a robust, high-performance industrial valve designed for reliable flow control and backflow prevention in demanding fluid handling applications. Constructed from **stainless steel (SS304 or SS316, depending on variant)**, this **lug-type double-flanged butterfly check valve** combines durability with precision engineering to ensure seamless operation in systems where bidirectional flow regulation is critical. The valve features a **resilient elastomeric seat** (typically EPDM or Viton, though wear may vary depending on usage) that provides a tight seal under pressure, preventing reverse flow while minimizing friction losses during forward flow. Its **235-series design** incorporates a **pneumatic or manual actuator interface**, allowing for either automated or manual operation, making it versatile for both automated and manual control systems. The **150-class rating** ensures it can handle pressures up to **290 psi (20 bar)** at temperatures ranging from **-20 F to 400 F (-29 C to 204 C)**, depending on the seat material, making it suitable for a wide range of industrial, chemical, and municipal applications such as water treatment, HVAC systems, and process piping.
The valve s **as-is condition** suggests it may have been previously used, though it retains its core structural integrity, allowing for reliable service in non-critical or secondary applications where cost efficiency is prioritized. The **lug-type flange design** (typically ANSI 150#) ensures secure mounting between pipes, reducing the risk of leaks while maintaining ease of installation and maintenance. The **single-disc mechanism** within the valve body provides smooth operation with minimal torque requirements, reducing wear on the actuator and extending the valve s operational lifespan. Additionally, the **SSVSR designation** indicates a **spring-assisted or gravity-assisted closing feature**, ensuring the valve automatically seals shut in the event of power failure or system pressure loss, which is particularly valuable in emergency shutdown scenarios.
Despite its used status, the **Marlin A-2-150 AS-IS** remains a dependable choice for applications requiring a balance of performance, cost, and reliability. Its **corrosion-resistant stainless steel construction** makes it ideal for handling corrosive fluids, while its **modular design** allows for easy replacement of internal components like the seat or disc if necessary. Whether integrated into a new system upgrade or repurposed for a secondary application, this valve delivers consistent performance with minimal maintenance, making it a practical solution for engineers and operators seeking a cost-effective yet dependable check valve solution.
### **Pros and Cons of Buying a Used Marlin Valve A-2-150 (As-Is, Butterfly Check 235, 150 SSVSR)**
#### **Pros:**1. **High-Quality Construction** Marlin valves are known for durability and reliability, often used in industrial and marine applications. The A-2 series is designed for heavy-duty service, making it suitable for high-pressure or corrosive environments.
2. **Proper Valve Type for the Application** The **butterfly check valve (235 series)** ensures one-way flow while minimizing pressure drop, which is beneficial in systems where backflow must be prevented without excessive resistance.
3. **Stainless Steel Construction (SSVSR)** The **150 SSVSR** designation indicates a **150# rating** with **stainless steel (SS) trim and seat**, making it resistant to corrosion from water, chemicals, or marine environments. This extends the valve s lifespan compared to carbon steel or bronze alternatives.
4. **Compatibility with Existing Systems** If the valve matches the piping size (likely **2-inch or 50mm**) and pressure rating of your system, it can be installed without major modifications.
5. **Potential Cost Savings** Buying used can be significantly cheaper than purchasing new, especially if the valve is in good condition. This makes it a practical option for budget-conscious buyers.
6. **Proven Performance** If the valve has been well-maintained, it may still function reliably, offering years of service without immediate replacement needs.

#### **Cons:** 1. **Unknown Service History** Since it s **as-is**, you don t know:- How long it has been in service.
- Whether it has been exposed to extreme conditions (e.g., freezing, corrosive fluids, or excessive pressure).
- If it has been properly lubricated or maintained (especially critical for butterfly valves).
2. **Wear and Tear on Moving Parts** Butterfly valves rely on a **rotating disc and seat**. Over time, the **seat rubber or PTFE lining** may degrade, leading to leaks or reduced sealing efficiency. The **shaft and bearings** could also be worn, causing sticking or increased friction.
3. **Potential Corrosion Inside** Even if the exterior looks clean, **internal corrosion** (from stagnant water, chemicals, or improper storage) could weaken the valve s functionality. Stainless steel helps, but if the valve was used in a highly corrosive environment, pitting or rust inside could still be present.
4. **No Warranty or Guarantee** Unlike new valves, you won t have a manufacturer s warranty. If the valve fails shortly after purchase, you ll bear the full cost of replacement or repair.
5. **Risk of Hidden Damage** Without a professional inspection, you may not discover:- **Cracked or warped disc** (common in butterfly valves).
- **Damaged shaft or actuator** (if it has one).
- **Leaking gaskets or seals** (which could lead to system contamination).
6. **Installation and Testing Challenges** Since the valve is used, you ll need to:- **Inspect it thoroughly** (visual check, flow test, leak test).
- **Potentially replace seals, gaskets, or lubricate parts** before installation.
- **Test it in your system** to ensure it operates correctly under your specific conditions.
7. **Resale Value is Zero** Unlike new equipment, a used valve has no resale value, so you lose that option if you decide to upgrade later.

### **Ending Conclusion:** Buying a **used Marlin A-2-150 butterfly check valve (235, 150 SSVSR)** can be a **cost-effective solution** if:- You **inspect it thoroughly** (or have a professional do so).
- You **test it under operating conditions** before full installation.
- You re **willing to invest time/money in maintenance or replacement of worn parts**.
- The valve is **critical for a non-critical system** (e.g., secondary water supply, non-pressurized applications).
However, if the valve is for a **high-pressure, high-reliability system** (e.g., primary water supply, industrial process, or marine engine cooling), the **risks of failure outweigh the savings**. In such cases, a **new or refurbished valve** may be the safer choice.
---
### **Recommendation:** 1. **If Buying Used:** - **Inspect the valve physically** for:- Visible corrosion, cracks, or deformities.
- Proper disc movement (should open/close smoothly).
- No leaks when tested with water pressure.
- **Test it in your system** before final installation.
- **Replace seals, gaskets, and lubricate** if necessary.
- **Consider a short-term trial** (e.g., in a non-critical line) to verify performance.
2. **If Uncertain or High-Stakes Application:**- **Purchase a new or refurbished Marlin valve** (if budget allows).
- **Get a professional inspection** before buying used to assess its condition accurately.
- **Check for alternatives** (e.g., a different valve type or brand) that may offer better long-term reliability.
**Final Verdict:**- **Good for:** Budget-conscious buyers with **low-risk applications** who can **verify the valve s condition**.
- **Not ideal for:** Critical systems where **failure could cause damage, downtime, or safety hazards**.
If possible, **prioritize a new valve or a trusted refurbished source** to avoid unexpected failures.
