Product catalog summary

FRIALEN Safety Fittings Overview
FRIALEN safety fittings, specifically the FRIASTOPP long couplers, are designed with integrated Mertik Maxitrol excess flow valves. These fittings are suitable for use with PE 100 SDR 11 pipes and are available in different types (Z, B, D) with varying maximum working pressures.

Specifications
The fittings are available in sizes ranging from 32 to 63 mm, with type Z and B supporting a maximum pressure of 5 bar for gas, and type D supporting up to 1 bar. The fittings are designed to be fused with pipes of SDR 11 to SDR 17.6, with a minimum wall thickness of 3 mm.

Areas of Application
FRIASTOPP is used in gas and service lines with operating pressures from 25 mbar to 5 bar. It acts as a safety device that automatically cuts off gas flow in the event of pipe damage. It is ideally installed between the mains and service line, behind the service line valve.

Functions
The FRIASTOPP system is divided into types D, B, and Z, each designed for different pressure ranges. Types D and Z include surplus flow devices that allow pressure to rise in intact pipes, enabling automatic reopening of the gas flow monitor system. Type B, without a surplus flow device, requires counter pressure to reopen.

Processing Advice
Installation should follow specific procedures, with the component's initial mains pressure indicated by a color-coded data plate. Fusion with the HD-PE service line is achieved using the FRIALEN fusion process, ensuring a leakproof and strong connection.

Benefits of FRIASTOPP

Factory-made combination of FRIALEN FRIALONG coupler and Mertik Maxitrol valve.
Enhanced installation safety with coiled pipes.
Optimum heat transmission due to exposed heating coil and wide fusion zones.
Traceability through additional barcode.

Excess Flow Valve Features

Precisely adjusted in the factory.
Low pressure loss and resistance to gas pollutants.
Applicable from 35 mbar to 5 bar, simplifying storage and reducing training costs.
