Multi-Hole, Orifice Plate

Metaval Orifice Plates are precision-engineered primary flow elements used in differential pressure flow measurement systems. Designed to meet international standards, these plates provide reliable, repeatable, and economical solutions for a wide range of process conditions.

Size Range:

From 1/2" (15 NB) up to 24" and above

Pressure rating :

ANSI 150# to 2500#

Design Standard:

As per requirement

Beta Ratio:

0.1 to 0.75 depending on type

Repeatability:

≤ 0.5% of flow rate

Application-Specific Use:

Quadrant & Conical types: Best suited for low Reynolds number flows.
Segmental & Eccentric: Designed for slurry or dirty service.
Multi-hole: Reduces noise, cavitation, and vibration.

Accuracy:

±0.5% to ±2% of full-scale flow rate

Flow Direction Consideration:

Required for non-symmetrical types (e.g., Eccentric, Segmental)
