Floor Spring Hold-Open and Closing Speed: What Each Model Offers

Updated 2026-11-08 · RAYEN 雷茵

What do the three features mean?

• 90° hold-open: open the door to 90° and it stays there until someone moves it.
• Two-stage closing valve: two adjustments that set the closing speed in two parts of the swing. The drawing shows which screw sets which.
• Closing force: how hard the unit pulls the door shut, given as an EN number. Within one model, the heavier grade always carries the higher number. D-5062 is EN3 at 60kg and EN4 at 100kg.

What should you decide before ordering?

• Must the door stay open by itself during the day, or close every time?
• Must you set the closing speed on site, for example for a slow, quiet close or a firm latch?
• Does your specification name a closing force?
• Is the door a fire door? Check your local rules on hold-open before you specify it there.
• Door weight and width, which pick the grade.

Floor springs

Read across. Every model holds open at 90°. The hydraulic models list the valve and an EN closing force, running from EN2/EN3 on D-5061 to EN6/EN7 on D-1067 and D-1068. The units without a valve show a dash in both columns.

Those units still matter. They cover a 304 stainless body (D-3012, D-3013, D-3015, D-3016), 8–12mm glass, and the heaviest doors in the range (D-3001 at 600kg). Choose them when hold-open and the load matter more than a set closing speed.

Overhead closers

Every overhead model holds open at 90°, have the two-stage valve and state a closing force, from EN3 to EN5. T-1078 and T-1079 are single action, and the others are double action. See single or double action.

Hydraulic hinges: hold-open over a range

Hydraulic hinges hold open differently. Several stay at any angle across a range, not at one fixed angle.

• RY8001 and RY8002 stay at any angle from 90° to 180°.
• RY8004 stays between 90° and 110°.
• RY8006 stays anywhere from 90° to 180°, with a positive stop at 160°.
• The JL series lists a hold-open range instead: 85–120° on JL606, 90–110° on JL607 and JL608, and 90–180° on JL609. All four have a closing valve.

RY8001, RY8002 and RY8004 also list closing speed as adjustable fast or slow without a tool. EK Type is cushioned at small opening angles.

Two worked examples

A shop entrance, open all day

A 45mm timber door, 80kg, 950mm from spindle to edge, swings both ways and stands open during trading hours. D-5062.100 fits: 100kg, ≤1000mm, door of ≥42mm, 90° hold-open, two-stage valve, EN4. At night it closes at the speed you set.

A heavy pivot door that must close slowly

A 60mm door weighs 280kg. D-3002.300 carries the weight but lists no valve. D-1067.300 carries 300kg at ≤1500mm with the valve and EN7, so the closing speed can be set on site. Choose it if the slow close is part of the brief.

Can a door hold open and still close at a set speed?

Yes, on every model that lists both. D-1032 holds open at 90°, has the two-stage valve and states EN3 or EN4 by grade. Push the door to 90° and it stays. Once it leaves that position, the valve decides how fast it closes. On the models without a valve, the door still holds open, but you cannot tune the close on site.

What should you write on the order?

• Model with grade, such as D-1067.300.
• Hold-open needed: yes or no.
• Closing speed control needed: yes or no.
• Closing force, if your specification names one, as an EN number.
• Door weight, width from spindle to edge, thickness and finish.
