## Long description

Two-pipe connection valve Varioterm Type V GZ3/4 x GW3/4 with straight nipples (model 000M856A001) is designed for plumbing and heating installations that use 3/4" threaded connections. The straight nipples provide a compact inline transition between supply and return lines in two-pipe systems, enabling reliable threaded coupling for radiators, boilers and other heating components. The valve body and nipples are sized for standard 3/4" fittings and are intended for systems where a space-saving, direct connection is required.
Advantages
The Varioterm Type V two-pipe connection valve offers a compact inline design that simplifies installation and reduces the need for additional fittings. Its threaded GZ3/4 x GW3/4 configuration ensures a tight, standardized connection compatible with common plumbing and heating components. Straight nipples maintain pipe alignment and support straightforward coupling of supply and return lines, helping to minimize potential leak points when properly installed.
Suitable for
Connecting radiators with 3/4" threaded inlets in two-pipe heating systems
Inline connections to boilers and heat exchangers with 3/4" fittings
Retrofit or replacement of existing two-pipe valve assemblies in compact installation spaces
Applications requiring direct, aligned supply and return pipe coupling
Key specifications
Connection type: straight inline two-pipe valve with male and female 3/4" threads
Thread standard: 3/4" external (GZ) to 3/4" internal (GW) threaded coupling
Design: straight nipples for aligned supply and return piping
Compatibility: intended for standard plumbing and heating fittings sized for 3/4" threads
Typical use: radiator and boiler inlet/outlet connections in two-pipe systems
How to use
Prior to installation, ensure the system is depressurized and drained as required. Inspect mating threads on pipes and fittings and clean any debris. Apply an appropriate thread sealant or tape compatible with heating systems to the male threads, then engage the GZ3/4 and GW3/4 connections by hand to start and tighten with suitable tools to the manufacturer’s recommended torque or to a secure, leak-free fit. Maintain pipe alignment while tightening the straight nipples to avoid cross-threading or bending. After installation, refill and pressurize the system, then check all connections for leaks under normal operating pressure and temperature.
Usage recommendations
Use compatible 3/4" threaded fittings and appropriate thread sealants rated for heating systems. Avoid overtightening to prevent thread damage; confirm alignment of connected pipes before final tightening. For installations in high-temperature or high-pressure systems, follow applicable local standards and consult a qualified installer if uncertain.
