Stopper, 1"

Product detailed description

Stopper valves are essential components in heating and plumbing systems, used to isolate sections of a circuit for maintenance or system adjustments. This model is commonly used in residential and commercial buildings, including central heating systems, hot water circuits, and industrial installations. Installers typically use these stoppers in conjunction with other threaded fittings to ensure a secure and leak-free connection. The nickel-plated finish provides corrosion resistance, making it suitable for environments where moisture or chemical exposure is a concern.

When selecting a stopper for a specific application, the operating temperature and pressure rating are critical factors. This stopper is designed for systems operating at a maximum temperature of +120°C and a nominal pressure of PN 10. These parameters ensure compatibility with a wide range of heating and plumbing systems, including those with hot water circulation and radiant heating. The external thread allows for straightforward installation using standard pipe wrenches and sealing compounds.

Technical parameters

Installation and connection

Installation of this stopper requires a 1 inch external thread connection. The fitting should be cleaned and threaded with a suitable sealing compound or PTFE tape to ensure a watertight seal. The stopper is tightened using a standard pipe wrench, ensuring that the thread is fully engaged without over-tightening, which can damage the sealing surface. Before final tightening, the thread should be checked for alignment and any debris removed to prevent leaks. Common installation mistakes include using the wrong sealing material or failing to clean the thread surfaces properly, both of which can lead to premature failure of the seal.

Compatibility and accessories

This stopper is compatible with standard plumbing and heating systems that use 1 inch external thread connections. It is typically used in conjunction with other threaded fittings, such as unions, elbows, and valves, to complete a circuit. For a secure connection, an EPDM O-ring is included to provide a reliable seal. No additional accessories are required for standard installation, but it is recommended to have sealing compounds or PTFE tape on hand for optimal performance.

Technical background for designers

The stopper operates by sealing off a section of a pipe, allowing for isolation of a component or section of the system. The EPDM O-ring provides a flexible and durable seal that can withstand the operating temperature and pressure. The integration of the stopper into a system depends on the system's design and the need for isolation points. Factors that affect the service life and efficiency include the quality of the installation, the condition of the sealing surfaces, and the operating conditions of the system.

Service and operation

Regular inspection of the stopper is recommended to ensure continued performance. Key checkpoints include the integrity of the sealing surfaces and the absence of leaks. If a leak is detected, the stopper should be removed and the sealing surfaces cleaned and re-sealed. No specific service intervals are provided in the brief, but it is advisable to inspect the stopper during routine maintenance of the system. The nickel-plated finish should be kept clean to prevent the accumulation of debris that could affect the seal.
