Installation; Recommendations For Installing The Valve; Before Installation; During Installation - Burkert 3233 Instruction Manual

2.1 RECOMMENDATIONS FOR INSTALLING THE VALVE

• Insert the valve into the process according to the standard
industrial practices (preferably according to ASME or DIN 11850
standards).
• Only tighten the manual actuator by hand!

2.1.1 Before installation

- Carefully clean the pipes.
- Remove all the pressures and tensible forces exerted on the valve by the pipes.

2.1.2 During installation

- Ensure the pipes are aligned.
- If the valve body must be welded onto the pipes, dismantle the valve (see § 4.2)
to separate the actuator and the diaphragm from the body to prevent them from
any damage.
- Preferably improve the surface quality by grinding the weldings.
- Carefully clean the body before mounting back the actuator and the diaphragm
(see § 4.2).

2.1.3 Installation of the valve 3233 for self-draining

- Incline the valve of 15° to 30° (depending on the DN) with respect to the
horizontal (see figure below)
- Install the pipes with a 3 to 5% minimum gradient in the direction of flow.
During the assembling of the valve in self draining position, the leakage detection hole
must be at the lowest point.
Self-draining in a process system is ultimately the responsibility of the
system designer and/or end user.
