2025年1月29日 · Nozzle check valves are designed specifically for scenarios in which a fluid, gas, or slurry is pumped in a low pressure or otherwise intermittent flow. In particular, they are meant to close quickly and quietly during low pressure and no-flow periods, and can be used to reliably prevent the liquid, gas, or slurry from flowing in the reverse ...

Removal of chatter associated with conventional valves in reciprocating compressor service. Protects rotating equipment from damage due to flow reversal. Minimizes pressure loss in piping systems. Spring tested to over 25 million cycles. Engineered product which can me optimised to suit system flow conditions.

NOZ-CHEK® valves deliver an effective dynamic response under various flow deceleration conditions. The dynamic performance characteristics of NOZ-CHEK® valves are compared to swing check and dual plate spring-assisted check valves in Figure 1. NOZ-CHEK®'s unique design features result in superior

NOZZLE CHECK VALVE Product Features • Nozzle check valves with bodies notably larger in diameter than their inlets display the best flow characteristics. • The disc faces for all of our nozzle check valves are designed to maximize hydrodynamic efficiency and minimize pressure loss.

The nozzle check valves characterise for an effective dynamic response under various flow deceleration conditions. Generally compared to other traditional check valves, the valve design is superior in performance, lower pressure drop ( depending size and form) and response.

2019年2月4日 · Compared to other check valve types, nozzle check valves offer unrivalled high flow, energy efficiencies and non-slam performance. They come with a selection of valve body and internal orifice designs and springs that are specifically optimised for the flow conditions of any given application.

Our nozzle check valves are available as forged or cast valves featuring exotic material options with short delivery times.

Our Non-Slam Nozzle Check Valve includes an optimized flow profile and unique dual-spring design to solve operational issues, including pressure loss and reverse flow, common with alternative check valve designs.

Proven reliability since 2008, our non-slam nozzle check valve*, characterized by an optimized flow profile and unique dual-spring design, solves common check valve operational issues while improving on the dynamic response and pressure loss of existing nozzle check valve designs.

Nozzle check valves are designed for situations where fluid, gas, or slurry is pumped at low pressure or with intermittent flow. They are specifically made to close quickly and quietly during low pressure or no-flow periods, effectively preventing reverse flow.
