Product catalog summary

Introduction
The document introduces the new GESTRA intermittent blowdown valves, specifically the MPA and PA models, which are advanced versions of proven designs. These valves are used for the optimal discharge of dangerous blowdown substances from boiler plants during operation.

Technical Highlights
The new PA 46 valve is based on the technology of the PA 26, with improvements that set new market standards. Key enhancements include:

Shifted pressure drop downstream to protect the valve seat.
Integration of a self-tensioning seal system for longer service periods.
Inclusion of a turbulence chamber and encapsulated tube structure for protection.
Compact design due to optimized material utilization, making it immune to waterhammer and pressure impacts.
External leakage check capability.

Benefits
The new GESTRA intermittent blowdown valves offer several benefits:

Improved blowdown effectiveness with an integrated pressure chamber.
Greater tightness with additional wiper rings.
Longer life and availability due to a radial stage nozzle.
Reduced wear from new seal arrangements.
Compliance with work safety regulations through a novel distance tube.
Quick and easy installation with multifunction parts.
Reduced maintenance through additional cup springs and external seal tensioning.
Enhanced checking functionality with a relief vent for leak detection.
Convenience with innovative clip fastening of the hand lever.

Design Innovations
The design includes:

An additional radial stage nozzle for reduced wear.
A patented protection tube and body forging for space economy and weight savings.
A check hole for targeted discharge of media leakage.
No large body cover, making the valve immune to pressure impacts.
Separate pre-tensioning of the seal accessible from outside.
Clip fastening of the hand lever for easy retrofitting and operation.

Conclusion
The GESTRA MPA and PA valves combine proven technology with new advancements, offering enhanced performance, safety, and convenience for industrial applications.
