BURKERT 463613 (Type 2000) is an externally piloted, pneumatically operated 2/2-way angle seat valve. It is operated with a single-acting piston actuator made of PA (Polyamide). High flow rates are attained with the virtually straight flow path of the stainless steel body. The reliable self-adjusting packing gland provides high sealing integrity. This maintenance-free and robust valve is designed for the controlled flow of liquid and gaseous media.

Control Function

Control function A (CFA): Pneumatically operated 2/2-way on/off valve. Normally closed by spring force.

Flow direction below seat: Designed for liquids, steam, and gases. As the medium pressure is under the pendulum disc, this pressure contributes to the opening of the valve. The flow inlet is under the valve seat.

WARNING

Risk of injury from bursting lines caused by water hammer! If the valve is used for liquid media when flow inlet over seat, water hammer may cause lines and device to burst. Do not use valves with flow inlet over seat for liquid media!

Dimensions

Actuator Dimensions

For actuator size 50 mm (D) and port connection DN15 (1/2"):

Actuator size ∅	∅ A [mm]	B / H [mm]	K / M [mm]	P	BS / HS [mm]
50 (D)	64	145	129	G 1/4	216

(Note: The dimensions for B, H, K, M, HS and BS are maximum dimensions and may be up to 6 mm less, depending on the nominal diameter and standard.)

Body Dimensions (Threaded Connection)

For NPT 1/2" (ASME B1.20.1):

DN	NPS	E (NPT) [mm]	CM [mm]	LM [mm]	SW [mm]
15	1/2	13.7	24	65	27

Installation & Operation

• Installation position: As required, preferably with the actuator upright.
• Control air connection: The control air connection can be aligned steplessly by rotating the actuator through 360°.

DANGER

Risk of injury from high pressure in the system! Turn off the pressure and vent the lines before loosening lines or valves.

TIP

Actuator Removal To remove the actuator from the valve housing, use an open-end wrench, never a pipe wrench. For control function A, pressurize the control air connection with compressed air (5.5 bar) so that the pendulum disc is lifted off the valve seat and is not damaged when screwed in or out.
