P7300 | Non-Freeze Dump Valve
BelGAS CP Control Products
The BelGAS CP P7300 Non-Freeze Dump Valve is a pneumatically operated liquid dump valve specifically engineered for vessel applications where freezing can occur due to rapid pressure drops. Designed with the trim fully contained inside the vessel, the P7300 utilizes process heat to prevent freeze-up and maintain reliable operation in cold or high-pressure environments.
This internal trim configuration eliminates one of the most common failure points in dump valve applications, making the P7300 a dependable solution for separators and gas processing systems operating under harsh conditions. The valve is designed for fail-close, pressure-open operation, providing controlled and predictable response during liquid level management.
With multiple trim styles available, including linear for controlled modulation and quick opening for on/off service, the P7300 can be configured to meet a wide range of process requirements. Material options such as hardened stainless steel and tungsten carbide ensure durability in abrasive and high-wear applications.

PERFORMANCE ADVANTAGES
Why the P7100 Performs Where It Counts
NON-FREEZE OPERATION
The internal trim design uses vessel heat to prevent freezing, eliminating a common failure point in traditional external dump valves.
RELIABLE LEVEL CONTROL
Designed for fail-close, pressure-open operation, the P7300 provides consistent and predictable liquid dumping performance in separator and vessel applications.
CONFIGURABLE FLOW CHARACTERISTICS
Available in both linear and quick opening trim styles, allowing the valve to be matched to either modulating control or on/off dumping requirements.
BUILT FOR HARSH SERVICE CONDITIONS
Durable trim materials and optional NACE construction ensure long-term performance in abrasive, corrosive, and sour gas environments.
