Refrigeration Safety Valve

A marine sounding cock is a compact manually operated valve installed in tanks aboard a ship. It is used to measure (or “sound”) the liquid level—such as fuel oil, fresh water, ballast, or sludge—by allowing a small sample to be drawn, or by inserting a sounding tape or rod.

Purpose of a Sounding Cock

• Enables safe and controlled manual inspection of tank contents
• Provides a method for sampling the tank's liquid at its lowest point
• Frequently utilised in:
• Fuel oil service and settling tanks
• Lubricating oil tanks
• Ballast and freshwater tanks
• Bilge and sludge tanks

We offer a range of Sounding Cock Valves from several leading manufacturers. Please get in touch with us to discuss your requirements. 

Introducing the NABIC 500T Combined Pressure and Temperature Relief Valve, expertly designed for unvented hot water supply systems that require both temperature and pressure protection. This innovative valve ensures optimal safety by allowing the pressure and temperature mechanisms to operate independently, thus delivering dual protection within a single unit. With the NABIC 500T, you can have peace of mind, backed by our industry-leading 5-year guarantee. **Specifications:** - **Sizes Available:** - 3/4" (DN15) - 1" (DN20) - 1¼" (DN25) - 1½" (DN32) - 2" (DN40) - 2½" (DN50) - **Connections:** - Male BSPT (Taper) Inlet - Female BSPP (Parallel) Outlet - **Materials:** - Gunmetal Body - Viton Seat - **Set Pressure:** - 1.0 to 12.5 Barg (DN15 to DN25) - 0.4 to 12.5 Barg (DN32 to DN50) - **Maximum Temperature:** - 95°C (Factory set at 95°C, non-adjustable) **Important Note:** The DN value embossed on the valve body indicates the NABIC 500 valve body size used in its construction and does not correspond to the inlet or outlet size. For instance, a valve with 1" connections (DN25) is built using a DN20 NABIC 500 valve body, hence the designation of DN20 on the valve's side. Upgrade your hot water supply system with the reliable NABIC 500T Combined Pressure and Temperature Relief Valve and experience unparalleled safety and performance.

This unit features a sensor with all electronics integrated into a single unit, designed to easily connect to your equipment. It screws directly into the body of the flow meter and delivers a 4-20 mA signal through a connector, making it compatible with instruments such as PLCs, computers, flow controllers, data loggers, and local displays.
