Frequently Asked Questions

Petro Sazeh Mihan is a Type 1 knowledge-based company. It combines engineering expertise, experience, research and innovation with modern machinery and testing equipment to provide industrial products and services.

For an engineering review, provide the fluid and its properties, required flow rate, operating pressures and temperature, flow capacity, and required materials. Include the project's control requirements and process conditions as well.

An oversized valve can add cost and make flow control unstable at low openings. An undersized valve may not deliver the flow required by the process. Selection should be based on actual operating conditions.

According to the product information, the 46000 series uses a 90-degree turn for shutoff and is intended for clean, contaminated, viscous, or corrosive liquids and gases. The stated attainable leakage class is up to Class VI.

The 38000 series is designed for precise control of low flow rates. Its product information highlights a compact design, anti-cavitation trims, and the option of custom design and manufacture based on customer proposals.

The 66000 series product page identifies cryogenic applications and a fire-safe design. Final selection should be checked against the project's operating conditions and technical requirements.

HP-HVOF stands for High Pressure High Velocity Oxy-Fuel. It is a thermal-spray surface-engineering process used to apply coatings resistant to wear, corrosion, and heat.

When the original design documents are unavailable, the existing product is examined and its components analyzed to recreate the design. The resulting design can then support product development and alignment with the latest applicable standard revisions.

The 38000 series product page states that design, seat and plug coating, machining, lapping, and routine tests are performed using PSM's dedicated equipment.
