Christian Bollin Armaturenfabrik GmbH products

Compact forged valve, with turned seat and internal spindle thread for short-time temperatures up to 300°C.Our valves have rolled spindles with a roughness < 0,002 mm. Therefore they offer security and long durability without any maintenance costs.

Forged valve with screwed stainless steel seat and screwed bonnet for universal applications. For higher temperatures (>250oC) with external spindle thread or for highest tightness (e.g. TA-Luft) with bellow and security-stuffing box available.

Pressure-gauge valves are applicable with simple applications for liquids, gases or steam with low pressure (PN6 / PN16) and a temperature from -10°C to +50°C.Use gaskets according to DIN 16258 (see page Z5) for the connection.Materials: Body Brass or Stainless steel (1.4571 / 316Ti)Handle: Polypropylene.

Gauge valves according to DIN 16270 specification with vent screw, but without test connection.

Forged steel, outside screw and yoke (OS&Y), Integral bonnet design, eliminates the risk of leakage across body-to-bonnet connections. Provides a more rigid construction. Full or conventional port. Integral stellited disc and seat. Rotating rising stem, rising handwheel.

This manifold is only for zero-point / equalization of an differential pressure gauge. The connections and the connection-measures can be adjusted to the differential pressure gauge.

Shut-off valve with screwed bonnet, back seating of the spindle and outside spindle thread.

This 2 valve manifold has an isolation and a vent / calibration valve.

Monoflanges are defined as flanges with integral shut-off valves in a variety of configurations. For shut-off purpose only a single valve assembly is available. The most common assembly however is shut-off valve combined with additional drain / vent valve, or two consecutive shut-off valves in combination with a drain / vent valve in a double block and bleed design. Whereas the Monoflange process side connects directly to the process flange, the instrument connection is either 1/2” NPT female threaded or features a swivel adapter with G1/2“ thread allowing for 360° free orientation of the instrument. Process flanges come in a number of different pressure ranges and sizes; therefore Monoflanges are usually tailor made to meet your specific requirements.
