Variety of stem types

Packing bolt for easy panel mounting, no packing

disassembling is required

Chevron stem packing provides lowest operation torques

Belleville washers to compensate packing wear

Special synthetic, anti-seize stem lubricant for best

resistance to hot media

VALVES & ACTUATORS

Packing bolt enables easy mounting with the packing remaining untouched

Belleville washers improve valve sealing, compensate for wear, and reduce the need for packing adjustment.

Chevron packing reduces packing bolt tightening torque, consequentially reducing the Valve operating torque.

Stem diffusion surface hardening provides the best

galling resistance and protection from wear and corrosion.

GENERAL

The H-300U Series is an advanced high pressure instrumentation needle valve for

shut-off service, its packing bolt design for easy mounting being the best solution for

instrumentation panels.

This compact valve enables a relatively high level of ﬂow regulation and long-life service.

Special stem surface treatment, based on low temperature carbon diffusion, enables

higher surface hardness with improved wear resistance, resistance to system

contaminations and optimal operational torque.

Notes:

Pressure (bar)

The H-300U was designed for high pressure services where moderately

uncontaminated media is used

For steam applications, it is recommended to select one of HAM-LET

severe service needle valves

For oxygen applications, select the oxygen clean treatment option.

For relatively high pressure pure oxygen applications, assure that the selected valve is tested and found to meet the speciﬁc application requirements

CLEANING & PACKAGING

Every H-300U series needle valve is cleaned in accordance with Standard Cleaning and Packaging (procedure 8184). Oxygen Clean & Lubricant Free Cleaning and packaging, in accordance with Special Cleaning and Packaging (procedure 8185), is available as an option.

Lubricant free cleaned valves have

signicantly higher actuation torque.

TESTING

The H-300U Series Needle Valve design has been tested for Proof and Burst. Every H-300U Needle Valve is factory tested with nitrogen at 1000 psi (69 bar). The maximum allowable leakage across the seat is 0.1 std cc/min.

PACKING ADJUSTMENT

Due to the varied service applications of the valve, packing adjustment may occasionally be necessary. Packing is factory adjusted to 1000 psig service. Initial packing adjustment is recommended after installation and prior to start-up. See packing adjustment procedure No.3901882 on the website.
