PSL-MD Marine Service Valve for Cryogenic Marine Applications

The PSL-MD Series is a light-pressure-type diaphragm valve developed to support stable operation under extreme low-temperature conditions. With proven performance in global marine markets, it offers a high coefficient of discharge, excellent seat tightness, and reliable functionality in harsh offshore environments.

Operating Range

Pressure: 1 to 250 kPa
Temperature: −196°C to +125°C

This wide operating range makes the PSL-MD Marine Service Valve suitable for cargo tank systems and auxiliary gas-handling equipment on liquefied gas carriers.

Technical Features and Advantages

Safe and Accurate Operation

The diaphragm structure ensures stable pressure control and allows adjustment of popping pressure even during operation, improving onboard operational flexibility.

Excellent Gas Tightness

A membrane seat structure minimizes the risk of gas leakage. PTFE sealing materials help prevent long-term degradation, ensuring continuous protection of valuable cargo.

Durability for Marine Use

PTFE diaphragms provide high corrosion resistance and long service life. The robust valve design reduces the risk of malfunction due to vibration or loose connections, contributing to lower maintenance costs.

Compliance and Design Flexibility

The PSL-MD Series is designed in accordance with IGC Code requirements and is available with multiple inlet standards and material options, allowing engineers to select configurations that match specific cargo and temperature conditions.
