Description

SP SERIES

HIGH PRESSURE,

POPPET TYPE,

SCREW COUPLINGS

INTRODUCTION

Holmbury High Pressure Poppet Type Screwed

Couplings are designed to withstand high pressures

and pressure pulses. High pressure pulses create forces

that act to separate the male and female couplings.

With couplings that use ball-in-groove retaining

mechanisms, the separating forces are concentrated

onto a relatively small area - point contact of the balls -

which can cause Brinelling (indentation of the balls into

the groove). Brinelling will lead to leakage and

eventually seizure of the coupling. Screwed couplings

have a screw thread retaining mechanism that

distributes the separating forces over a large surface

area, thus eliminating brinelling.

FEATURES

 Screw thread retaining mechanism to

eliminate brinelling

 Connection and disconnection can be performed

even with a low residual hydraulic pressure in the line

APPLICATIONS

Mobile plant, agricultural implements and general

industrial equipment.

MATERIALS

Zinc plated carbon steel body material with nitrile seals

and PTFE backing ring.

TECHNICAL DETAILS

Working temperature range with nitrile seals is

-20°C to +100°C

Couplings are also available with Viton seals for an

operating temperature range of -15°C to +180°C.
