Selector ball valve for manifold mounting Steel PK3

Product catalog summary

Overview: This document provides technical specifications and details for the PK3 series selector ball valves designed for manifold mounting. The valves are constructed from steel and are available in sizes ranging from DN6 to DN50 (1/4" to 2").

Specifications:

Materials: The body, ball, and stem are made of steel, with ball seats made of POM and O-rings available in NBR or FPM.
Temperature Range: The operational temperature range is from -20°C to 100°C.
Porting Pattern: L=SB58 for both 112A and 1128 material codes.
Pressure Inlet: Only from the center port (port 2).

Dimensions and Weights:

Detailed dimensions are provided for each valve size, including lever weight and other critical measurements.
Weight varies from 0.60 Kg for PK3-DN6 to 28.80 Kg for PK3-DN50.

Flow Characteristics:

The document includes a flow characteristic graph showing the relationship between flow rate (Q in l/min) and pressure drop (Δp in bar) for different valve sizes.

Connection Dimensions:

Specific dimensions for screws and torque requirements are provided, with recommendations for screw types as per ISO4762 (DIN 912).

Additional Information:

Accessories available on request include locking devices, actuators, position switches, and detents.
Material codes may vary due to availability, but suitability for application remains consistent.
