Specification

What is Valve Base (Bottom for Valves)?

A valve base is a standardized mounting interface that securely connects an actuator to a valve body, ensuring precise alignment, torque transmission, and leak-proof sealing.

Function

1.Superior Leak Prevention:

Integrated Sealing Surface: Features a precision-machined interface designed to accommodate a standard O-ring or gasket.

Positive Seal Formation: Creates a reliable, leak-proof barrier between the valve body flange and the actuator base when tightened, preventing fluid escape around the valve stem or through the mounting interface.

Robust Construction: Ensures structural integrity under pressure and torque, maintaining seal integrity.

2.Effective Valve Stem Protection:

Environmental Shield: Acts as a protective barrier, covering the valve's top works (including the stem seal packing and upper stem section).

Contaminant Exclusion: Helps prevent ingress of dust, dirt, moisture, corrosive agents, and other environmental contaminants that could damage the stem seal or cause stem corrosion/binding.

Mechanical Guard: Provides a degree of physical protection against accidental impacts or abrasion to the critical stem area.

3.Essential Component of Valve Assembly:

Critical Interface: Forms the foundational mounting component between the valve body and the actuator.

Integral to Valve Function: Directly interfaces with the valve's mounting flange (typically conforming to ISO 5211 or equivalent) and transmits actuator torque to the valve stem.
