Guarantee provisions
This document contains no warranty statements. Please refer to our general
terms of sales and business. The prerequisite for the guarantee is the use of the
device in accordance with the prescribed operating conditions.

CAUTION!
The guarantee only warrants that the valve, Type 2000/2002, is
free of defects. No liability is accepted for loss or damage of
any type resulting from failure or malfunction of the device.
2002) consists of a pneumatically operated piston actuator and a 2/2-way
valve body (angle-seat valve Type 2000/2002) / 3/2-way valve body (globe
valve Type 2002). The actuator casing is manufactured of polyamide (PA) or,
alternatively, polyphenylene sulfide (PPS) for special applications. The timeproven, self-adjusting packing gland ensures high seal integrity. The flow
optimizing valve body made of gunmetal (bronze) or stainless steel enables high
flow-rates.

Requirements placed on the closing behaviour of angle-seat
valves by DIN 1988 Part 2
To satisfy the requirements of the push-through test to DIN 1988 Part 2, the
exhaust air must be throttled with a throttle having a maximum diameter of 1
mm.
The flow restriction options are as follows:
• Integrated construction of a restrictor or a one-way flow restrictor directly
in the pneumatic actuator.
• Restrictor in the exhaust air port of a 4-way pilot valve.
• Restrictor or one-way flow restrictor directly at the outlet of a
3-way pilot valve.
Bürkert offers the appropriate valves for this purpose.

COMMISSIONING
Installation of valve
Mounting position: any; preferentially with the actuator oriented upward.
➔ Install in accordance with the flow direction.
CAUTION!
In all cases, remove all contamination from the piping (excess
sealing material, metal debris, etc.).
Procedure for installing the valve:
➔ Connect the valve. Make sure the pipe run is correctly oriented.
➔ VA/VS body w/ weld ends: Disassemble and remove actuator before welding.
➔ Threaded body: Only disassemble the actuator if required by customer.
Instructions for actuator disassembly and assembly
Disassembly:
➔ Depressurize the valve seat before the removing and reassembly.
➔ Control function A: Turn on the actuator or release the tension of the return
spring by removing the actuator cover.
➔ Control function B or I: Switch off the pilot pressure.
➔ Screw the threaded nipple out from the body.
Assembly:
➔ Only for the stainless steel body: Grease the nipple threads with a suitable
lubricant.
➔ Screw the threaded nipple and the actuator into the body.
